I do not see fileName in your code. Which line is throwing the error?

Doug

thanks a lot for all the great tutorials on Matlab. I really learned a lot from you. ;-)

But know I am stucked with a simple problem for hours. I want to save an list of arguments to a variable in the beginning of my m-file so that I can configure the plotting options for all plots at once.

I tried the following to define the options list:

LegendText={‘Location’,'SouthEast’, ‘Interpreter’, ‘latex’,'FontSize’,16};
PlotOptions={‘MarkerSize’,5,’LineWidth’,1,’DisplayName’,FileName{i}}

But this does not work when calling the functions

for i = 1:10
plot (x,y{i},PlotOptions);
legend1 = legend(‘show’,'-DynamicLegend’);
legend ([legend1, LegendText])
end

Do you have any idea how to use “dynamic field names” in the argument list with a variable which is later running in a loop (in this case the variable FileName{i})??

Thanks a lot in advance for any tip!

shading flat

or

shading interp

In this last case, the shading of the surface plot will be interpolated.

You will need to pull the value of the cell array out, then delete it, and put it back in the cell. You can not do this in one operation.

Can you please help me with this problem?

Usually I need to do some cropping when pasting copied figure to e.g. Powerpoint.

Thanks,
Matti

That’s how I’ve been doing it for years, but just last week that method started consuming 50% of my processor bandwidth and taking minutes to complete. It doesn’t happen on simple plots, but does happen on mesh plots of 200×400 matrices.

My workaround is print -dmeta. That works, but Copy Figure essentially hangs the computer. Three different computers, all running R2011b.

This could be many things, but it’s good to start by finding out if it’s a systemic problem or just me.

Thanks!

In my experience many Matlab programmers are surprisingly unaware that they can turn profiling on and off at will, interactively or programmatically, while a Matlab program is running. Doing so can significantly improve our profiling and performance-tuning effectiveness.

I don’t normally use dedicated GUI controls, since this “soils” my GUI, and I’d need to update the layout. Instead, I typically just run

profile on; ... profile off; profile report"


from the Command Prompt just before starting the workflow-to-be-analyzed. Simpler still, I click the “Start/Stop profiling” button in the Profiler tool. Another simpler alternative is to create two simple shortcuts in the Desktop that start/stop profiling respectively. This obviates the need to update numerous different GUIs separately.

In a related note, I often use the technique of selective workflow profiling to understand how a customer’s GUI behaves and works. I start profiling, interact with a specific GUI part, and then stop profiling and look at the detailed report to see what the code did in this time. It is then easy to step right into the relevant part and start coding/fixing. Customers are often surprised how quickly I can understand and fix their code, when it’s really just the selective use of the Profiler… Let’s keep this trade secret between us, shall we? :-)

You can put whatever code you like in the function. Beware of what variables are in and out of scope and the order things are called, but yes, you should be able to do what you are talking about.

1. It clashes with GUIDE, making GUIDE unusable (verified bug reference 1-MH5KVI)
2. It apparently causes memory leaks in the new desktop Editor, causing increasingly large delays whenever a breakpoint is encountered and exited (unverified, but also reported by others in forums)

Hopefully these bugs will be solved soon, since this is such an important debugging mechanism.
