[…] This wrapper function can then be placed within a @char folder somewhere in the Matlab path. I used a similar trick for my profile_history utility last month. […]

In reply to Dan. @Dan - I uploaded an update to the profile_history utility with the ability to programmatically and interactively control the number of displayed functions (default = 15), sorted by descending total time.

It might be useful to be able to put a option to limit the number of function levels in view (i.e. How many sub-functions you delve down into for displaying their commands) … such that your not displaying so many commands. That could help visualize the general problem areas and let you dive down into those without getting so many display objects on the figure (which ultimately stops he usefulness).

In reply to Wes Brodsky. @Wes - the title might change a bit by the time it actually gets published in a few months, but the ISBN and web link will remain unchanged.

Sounds great! I have not had a chance to try it yet. I look forward to the publication of your book;

In reply to Ali. @Ali - thanks, I just updated the FEX utility with a fix to this edge-case.

Dear Yair, When I run the code

profile on; surf(peaks); profile_history

I get the following error message:

 
>> profile on; surf(peaks); profile_history
Error using copyfile
Cannot write to destination:
/home/ali/Documents/MATLAB/@char/profile_orig.m.  Use the 'f' option to override.

Error in char/profile (line 10)
    copyfile([matlabroot '/toolbox/matlab/codetools/profile.m'], [curFolder '/profile_orig.m']);

Error in profile_history (line 42)
        profData = profile('info');

However, when I removed @ from the @char folder's name, it works like a charm.
