Advanced MATLAB: Compiling a GUI

This video shows how to use DEPLOYTOOL to create a project and compile it so that it can be used outside of MATLAB, meaning you can give it to someone that does not own MATLAB and they can still run it. This is useful in a variety of situations, for example you might want to lock down a functioning GUI so that even as you upgrade MATLAB you will know that your GUI will not change, because it is a stand alone. You might want to obscure your algorithms from people you give your code to. The demonstration is using an add on product called: MATLAB compiler http://www.mathworks.com/products/compiler/

    Very useful guide. But when I went to the deployment tool, “windows Standalone application” was not one of the options. Also, when I tried to run the deployment tool on a GUI i created, it asked which compiler I wanted to use. Is there a specific one that needs to be used? Also, how do you generate and send out the MCR file that you discussed? Thanks!

  2. Dave Forstot replied on :

    The MATLAB Compiler deployment target “Windows Standalone Application” was new with MATLAB R2007b. Older versions only had the “Standalone Application” option - the difference being the new Windows Standalone Application does not start a command console (dos box).

    The first time you use MATLAB Compiler, it needs to be configured to use a compiler. There is a list of supported compilers on The MathWorks website (TechNote 1601):
    http://www.mathworks.com/support/tech-notes/1600/1601.html

    You can include the MATLAB Component Runtime (MCR) with your MATLAB Compiler generated executable by using the packaging feature of deploytool. By default the MCR is not included with the executable because of its size. However, if you go into the deploytool settings, under packaging, you can optionally choose to include it. This tab will also show you where the MCR is located on your file system if you want to distribute it separately.

    Good luck!

  3. Jim Strickland replied on :

    Thanks very much for this tutorial. I have R2006a - could you show how I can compile a GUI using this version?

  4. Doug replied on :

    Jim,

    R2006a did not have the deploytool. If you contact support

    http://www.mathworks.com/support

    they can give you details on how to do this. You might even be able to upgrade to the newest version of MATLAB, depending on what you company has purchased.

  9. Dave Forstot replied on :

    liantaodu and Marco Trincavelli,

    I was unable to reproduce this error in MATLAB R2007b on windows.

    I copied your code exactly from above, and used the same compiler command. The resulting application behaved the same as the MATLAB function.

    Perhaps this was an issue that already been addressed by the developers?

    very nice show!
    But i am not being able to access the deployment tool.
    I’ve written deploytool and pressed enter. But it replays me undefined function…
    So, what to do… i must be greatful to you…

  13. Tapon replied on :

    I have seen this video more than 20 times but not getting the answer how to access the deploytool?
    Please help me!
    My Matlab version is 7.1
    Is it a problem for not finding Deploument Tool?
    please answer me as soon as possible… i am in a big trouble!

  14. Doug replied on :

    Tapon,

    This is an additional product:

    http://www.mathworks.com/products/compiler/

    You need to purchase the MATLAB Compiler for this function.

    Doug

  15. Jiro replied on :

    Tapon,

    Also, if you do have MATLAB Compiler, “deploytool” was added to the product in R2006b. If you have an older version of the MATLAB Compiler, you need to use the command line functionality (mcc).

    jiro

  16. Tapon replied on :

    Thanks! for reply…
    It will be my pleasure if you give me the answer of following…
    I made a GUI and saved the m.file in the work directory. thus wrote the command [mcc -mv filename.m] in the command window.
    It generates a filename.exe file. this file is executabe.
    But it doesnot run in a machine where matlab has not setup. Now i want to make an application that will run in any in any machine independent of Matlab…
    is it possible?

  17. Jiro replied on :

    Tapon,

    Which version of MATLAB are you using? Does the .exe file run successfully on the same computer?

    You have to install the MCR on machines that do not have MATLAB. Take a look at the documentation for MATLAB Compiler (there might be a section called “Deployment Process”)

  19. Julio replied on :

    Dear Doug,

    Your video is excellent. I’m using Matlab R2008a and have a problem. I used the deploytool and compiled a program I’m coding for Line Codes. It uses 2 .fig GUIs and 4 .m files (2 for figures and 2 as support for the figures). The 2 GUIs are the splash screen (with my name on it) and the main screen. So on the deploytool I put, as main function, the splash.m file. Then I compiled.

    The program runs great in MATLAB, but the exe file seems to open and close really fast (not showing anything). If I compile using mcc -e, the program works but I cannot run it in other non MATLAB computers. I also saw that MCR Installer is at “C:\MATLAB\toolbox\compiler\deploy\win32\” Can I take that installer to other computers, run it and then run my program compiled using mcc -e? Or do I need to package it using deploytool? Why is my program not working with deploytool?

    Thanks a lot! Keep up the great work!

  21. Julio replied on :

    I’d like to add something to my comment. I’ve noticed that doubleclicking on the .exe file doesn’t extract the ctf file as you show in your video. Is something wrong with what I’m doing? Maybe an option was left behind where I should’ve clicked.

    Thanks!

  22. Jiro replied on :

    Julio,

    In R2008a, the extracted CTF files can be found at

    USERPROFILE\Local Settings\Application Data\MathWorks\mcr_cache_v##\
    

    where USERPROFILE is your Windows user profile directory.

    I would suggest creating a regular Standalone Application (not Windows Standalone). Then open up a DOS prompt, and run the executable from there. You should see any error messages that may pop up in the process.

  23. Julio replied on :

    Jiro,

    Thank you very much. I debugged using the technique you told me. I found out that my png pictures weren’t found by the program because I didn’t include them in the “other files” section in deploytool (since I followed Doug’s video, but he didn’t use any images).

    So, I think this will help Mukund, if you ever have files other than .m or .fig, include them in the Other Files section or the program will not work.

    I have another question though. If there’s a new release of MCR (for instance, in MATLAB 2009a), will my program in 2008a (compiled exe file) work in the new MCR? Or should I save a copy of the old MCR.

    Thanks again guys, keep up the great work!

  24. Jiro replied on :

    Julio,

    I just want to mention one thing. If the images that you are loading with your program are something that you always need together with your program, then yes you need to add it as “other files”. This is true for any other files that your application needs to “load”. But if your application is meant for loading an arbitrary image that the user specifies, then you shouldn’t have to include them in the application. In this case, one of the common mistakes is that people use just the file name, instead of the complete path of the file. For example, instead of

    filename = uigetfile('*.png');
    im = imread(filename);

    you should use

    [filename, pathname] = uigetfile('*.png');
    im = imread(fullfile(pathname, filename));

    This will ensure that your function will work regardless of where the image file is on your computer.

    Regarding your question about MCR, your application will only run with the same version of MCR used to deploy. So your application compiled in R2008a will not run on R2007b or R2008b MCR. But, multiple versions of MCR can co-exist on a computer, and your application will automatically choose the appropriate MCR. That means that when you create other applications in future releases, those applications can run with the new MCR, while your old application can also run on the same computer using the older MCR.

    Hope this helps.

  25. Julio replied on :

    Thank you very much Jiro. Your comment completely helped me and also gave me a new perspective on user specifying a specific file. My images were my University’s logo and a flow chart in png, so those weren’t to choose. About the MCR, do you recommend to package the MCR on every deployment? or instead of that to have copies of every MCR Installer that is released?

    Thanks again!

  26. Jiro replied on :

    Julio,

    I think it really depends on your situation. If you are deploying to only a few computers, it might make sense to install the MCR each new release that you get. If you are distributing to a large number of end users, it might be better to package together the MCR with your deployment. Or you may only want to provide the MCR for the first few applications.

    Hi Doug. I’m using MatLab 2008a and trying to compile a GUI with an uitable component. The GUI is running great on MatLab but it doen’t work in the standalone application. Do you know what is happening and how to fix it?

    Thanks in advance.

  28. Scott Hirsch replied on :

    This is a known limitation. See the discussion here, with a workaround suggested by one user:

  29. mak replied on :

    hi all,

    i have the application which will take the commands from the GUI and read the data available from files. The m file then process the data. So overall i have the application with m files, fig files, text or excel file, and logos stored at different directories.
    i want to bulid the .exe. i am giving initial script as the main file and all other files(logos, m and fig files) under other files. it is creating the .exe but after running it, the GUI is quitting (irrespective of waitfor command while calling the fig).
    i hv the set of script and function m files. is it due to this. or is thr any other reason for the same.
    could u please guide me for the problem..

    Thanks…

    Hashem,

    Take a look at this documentation:

    It talks about the ‘-e’ option to suppress the command window. Give it a try.

    Doug

  32. Moran replied on :

    Doug,
    Bringing back a previous discussion topic - compiling a GUI which contains table objects. Unfortunately, I switched to R2008a to be able to use the new uitable, which is exactly what fails to compile properly…

    I’m aware of the discussion here: http://www.mathworks.com/matlabcentral/newsreader/view_thread/166196#431145

    Indeed, including arrayviewfunc.m and workspacefunc.m in the compilation helped in eliminating the errors. However, the issue of a non-numeric table showing blank cells remains unsolved. Is there any news with regards to that?
    Is there a reasonable workaround that I can use in the meantime? (switching the object’s parent after each call to ‘drawnow’ works, but since I continuously update a plot in that figure - it causes the table to flicker).

    Thanks!
    Moran

  33. David replied on :

    Hi,

    I am not able to run the ‘deploytool’ on my Matlab 2007a. ??? Undefined function or variable ‘deploytool’ is the error message received. Pls let me know how I can run this tool.

    Thanks.

  34. Steve L replied on :

    David,

    As Doug mentioned back in comment 14, DEPLOYTOOL is part of MATLAB Compiler. You can check if you have MATLAB Compiler installed by calling the VER function and checking for it in the list of products.

  35. Joanna replied on :

    Hi Moran,

    You can go to http://www.mathworks.com -> Support. Login then choose ‘Bug Reports’. The bug report ID is 449936 - ‘Unable to deploy applications that contain uitables’. Downloading the patch file and following workaround instructions… Good luck!

  36. Moran replied on :

    Hi Joanna,
    Thanks for the reply. However, this takes care only of the compilation errors (equivalent to including arrayviewfunc.m and workspacefunc.m in the compilation) and does not solve the problem of non-numeric tables showing blank cells.

    Looks like bug report # 456568 ‘Compiled GUIDE GUIs that contain UITables do not show table data at run time’ refers to the problem I’m encountering. No workaround provided yet.

    Hello Doug,
    Great article.
    I have matlab r14 sp3.
    I noticed one thing when I was making a standalone application of my GUI. My GUI had uigetfile and errdlg functions. When I do
    mcc -m mygui.m
    it makes a mygui.exe (and .ctf) file which works fine with all the uigetfile and errdlg functionality, but, the command window in the background freezes and cannot be moved or minimized.
    This is only true when the gui code in the background uses the uigetfile or errdlg functions. While using other functions/commands, the background command window doesn’t freeze and can be minimized.
    Any thoughts?

  40. Scott Corzine replied on :

    I am using R2008a and am using the deploytool to create a standalone GUI application. The exe generation part works fine. Where I am having trouble is figuring out a way to get the path of the standalone executable that the user double-clicked. The ctfroot command points to a place in Local Settings\Application Data\…\myApplication which apparently gets generated on the fly when I first run the executable and it recreates all o fthe .m files in that location. This is not the directory I want. The directory I want is the directory in which the user double-clicked the original standalone .exe file. This is because I have a subdirectory in that directory where the user can place files for my program to load. So I need to know where the original .exe file is so I can locate the subdirectory. pwd and matlabroot do not work either. Any ideas?

  42. Scott Corzine replied on :

    It turns out I was able to solve my problem by disabling my startup.m script using the isdeployed flag with an if statement around the entire code block.

    I normally use the startup.m file to automatically switch matlab to my current project folder of interest. I didn’t realize that when you deploy a standalone application, the startup.m file gets sucked into the mix, even though it is not in the list of m-files in the deploytool project! Perhaps there is a setting I haven’t found that can disable this “feature”.

    So when I ran the standalone executable, it was actually running a copy of my startup.m file before launching! This was changing my default pwd path. Once I set the startup.m to run like

    if ~isdeployed
    …startup code…
    end

    then pwd pointed to the correct path where the standalone executable lives.

    Hi Doug,
    I am creating a graphical interface in Matlab 7.0.1. My interface as images and when I use the mcc compiler it does not compiles the images, I mean it creates the .exe file but when I try to use it it requests the .jpg files to be in the same folder taht the .exe created. Is there an option in this version of the Matlab compiler (as it does not have the deploytool) that allows me to create a stand alone application that does not need to have the images together with it to run?

    Thanks in advance,

    If your program reads in the files, you will need to include them since the compiled version will work the same as the MATLAB one.

    Hi!

    Apologies for banging the ‘uitable compile-error’ drum once again (see 32, 36 etc above), but does anyone know whether a satisfactory workaround or fix has been produced to overcome the problem of values/text disappearing from a GUI table in its ‘compiled’ form?

    I’ve discovered that, although info disappears once the user has clicked onto another table cell of the compiled GUI, the data entered is still comitted to memory for use in subsequent calculations - it just isn’t visible in the table cells. Most frustrating! We too upgraded to R2008 for this purpose - so any help would be gratefully received.

  52. Moran replied on :

    Hi Chris,
    I tried everything I could think of, and have sent several observations about this bug to support, but eventually lost all hope that this bug will be fixed in the immediate future (it has been already 2.5 months since I encountered it).

    Fortunately, a great alternative exists! Check out Yair Altman’s “CreateTable.m” code:
    http://www.mathworks.com/matlabcentral/fileexchange/loadFile.do?objectId=14225&objectType=file

    The examples that Yair supplies make it very easy to learn how to use it, even for someone with no previous experience with Java (like me…). Furthermore, this works great (and compiles) on previous versions of Matlab, so no need to upgrade to R2008x, and you can enjoy the much smaller MCR file size (150MB in 2007a vs. 240MB in 2008a).

    Hope this helps,

    Hi Doug,
    I would like to ask you an opinion. I am developing in MATLAB R2008b a very complex matlab application with a main gui and several child guis. It involves images, simulink models and many s-functions (both matlab and c/c++ s-functions). I would like to ask you if a multiple gui project could be a problem for the compiling process and if the MATLAB compiler is able to compile both matlab code and simulink models togheter. If so, do I need to include all the simulink related files (like .mdl files and the s-functions) in deploytool?
    Many thanks for any kind of help and thanks for your interesting blog.

    Dan

    Dan,

    Simulink does not “compile” with the MATLAB compiler. I think you might need one of the Real Time Workshop targets to make that happen.

Wrap code fragments inside <pre> tags, like this:

<pre class="code">
a = magic(3);
sum(a)
</pre>

If you have a "<" character in your code, either follow it with a space or replace it with "&lt;" (including the semicolon).
