MATLAB Profiler - Granularity of Information

19 views (last 30 days)
MATLAB Profiler produces very coarse granularity of performance statistics on a model I'm developing and testing:
  • # of times a routine is called;
  • Total Time, and Self Time.
However no information is provided on other routines, including MATLAB primitives, called. Can this finer grained information be obtained from Profiler?

Yes, I'm aware of Altman's book and plan to purchase it as a reference. The graphical feature should be useful. However, access to the data from which the graphs are produced is also of interest to our team. Thanks for this reference.

There are four technical articles on Undocumented profiler options on Altman's web-site. And he mostly provides good answers to specific questions in the comment sections.

Use the [undocumented] -detail builtin profiler option, as in: profile on -detail builtin
This works on old Matlab releases as well as new ones.

This got better in R2020a with the new interface to the profiler.
