profiler tool with GUI file

Dave Brackett — Mon, 06 Oct 2008 16:24:03 -0400

Hi,

I have a GUI which controls an m file. After some user interaction to change settings, the function runs for some time. I want to profile the code to identify areas for improvement, but when i use the profiler tool to run the m file with the GUI, it starts profiling but stops almost immediately once the GUI loads.

How can I use the profiler tool to assess the m file which has the GUI?

Thanks.

Does the profiler stop or does your code stop because of a uiwait() in the GUI code?

If its the code, fill in the GUI and click OK (or whatever label you have). That should issue a uiresume() and start execution again.

For profiling guis I find it works best to set up the gui, type "profile on" in the command window, let the gui do whatever you want to profile, and then type "profile viewer" in the command window.

thanks for this tip matt, I didn't know you could access the profile tool in that way.
