debugging 'hierarchical' code stored in different folders

Hi all

My file structure is:

./func/<functions>.m

./<main>.m

If I execute main.m, and the main.m file calls different function.m (in ./func/), then breakpoints are ignored in my main.m file.

If the current folder in the matlab GUI is not the same like main.m, then I either get an error message or the program runs empty, i.e. does not execute.

Anybody ever seen this? Any suggestions?

I run 7.11.1.866 (R2010b) Service Pack 1 on Linux ... 2.6.32-131.17.1.el6.x86_64 #1 SMP Wed Oct 5 17:19:54 CDT 2011 x86_64 x86_64 x86_64 GNU/Linux

Thanks for your help

Erich

Your MATLAB GUI -- is that designed using GUIDE? If so then it probably codes most callbacks as strings instead of as function handles; callbacks coded as strings are evaluated at run-time in the base workspace, so a referenced routine might not be found at run-time because you have changed directories.

You can add the directory that main is found in, into the MATLAB path, or you can recode the callbacks to use function handles instead of strings.

I don't know.

All paths are definitely included in Matlab paths.
