# MATLAB Basics: GUIs without GUIDE10

Posted by Doug Hull,

GUIDE is the standard way of creating GUIs in MATLAB, but sometimes it is better to make the GUI programmatically. This often happens when you want to easily create and destroy buttons and other widgets during the course of the GUI’s use. Handwritten code is often more compact and gives… read more >>

This is the next in a series of advanced topics in MATLAB. My definition of “Advanced” is somewhat nebulous and arbitrary, so even newer users can give this a watch. Two and a half minute video shows how to use buttondownfcn to get the current point. This can be a fundamental… read more >>

# MATLAB Basics: Functions and subfunctions7

Posted by Doug Hull,

This six and a half minute video shows a function being created in MATLAB, then it shows a subfunction being added. Functions are a way of adding to the MATLAB language. This video shows the creation of a simple function, and then adding a subfunction to that original function. @media (min-width:… read more >>

# Practical Example: Visualizing the density of a data cloud3

Posted by Doug Hull,

I was working with a MATLAB user that had a large number of data points in the form of x,y,z triples. He was mostly interested in the density of these data points over the range of the data. At first he tried to just do a scatter plot, but there… read more >>

# Advanced MATLAB: Compiling a GUI63

Posted by Doug Hull,

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… read more >>

# MATLAB Basics: Parsing code for better understanding1

Posted by Doug Hull,

This six minute video shows you how to use the debugger and other tools to step through complicated code and understand what is really going on. By taking a complicated expression and breaking it into smaller pieces, you will have a better idea of what is really going on. @media (min-width:… read more >>

# Advanced MATLAB: Data acquisition in MATLAB24

Posted by Doug Hull,

MATLAB is often used for post-test data analysis. You can get more value from your data acquisition session if you do the MATLAB analysis on the data as it is being collected. This can be done by having MATLAB be the software for collecting your data. This video shows a very… read more >>

# MATLAB Basics: Scalar and Vector expansion

Posted by Doug Hull,

Two minute video explains scalar and vector expansion. This helps in situations where you are adding a scalar to a matrix and shows how to expand a vector for a similar effect. @media (min-width: 992px) { .containing-block { width: 100%; } }   Other videos have been gathered here: http://blogs.mathworks.com/pick/category/video/ Other MATLAB Basics posts have… read more >>

# Coaching call to debug GUI1

Posted by Doug Hull,

This video is a departure from my other videos. This video captures a coaching call between Edgar and me as we debug a GUI that Edgar had created. This video was completely unscripted and has only been lightly edited, so it is longer than my normal videos. This shows how an… read more >>

# Practical example: Setting transparency on a patch2

Posted by Doug Hull,

First, be sure to check out the new home of LazyWeb. We had three of the challenges closed, but there are three still open. We are sending out MATLAB prize packages to all that solved a challenge, and look forward to sending out more as the rest are tackled. Here is… read more >>
