Hi, I am trying to produce a code that plots certain information in a gui figure so that the user can make a decision, based on the plot, which function to execute next. The functions are executed by buttons on the gui figure. As the functions are triggered by callbacks if I try to debug as normal I am not able to access the function. How can I get into the function to find my error?
Thanks

"[...] debug as normal [...]"? Could you provide an example? I would either set
>> dbstop if error
or set a breakpoint in the callback function before I fire the callback.
Here are some links on debugging in Matlab

Sorry, I should have been clearer. debug as normal was in reference to the manual method of adding break points in the scripts and waiting for the code to reach that point. dbstop is a fantastic tool. I am thankful for learning of it.

I'm glad the tip was helpful. See above, I added three links on debugging in Matlab.

There is info on debugging a GUI here, both in the video and the comments.

Breakpoints in callbacks work only if you also set a breakpoint in the caller function/script. So, you could add a line of pause(0.1); to the caller function/script and set a breakpoint there. When the caller is stopped at that breakpoint, the breakpoint inside the callback will work as well.
