Hi, I've a simulation that takes nearly an hour to run for 1 iteration. I've been using tic and toc to determine what sections take longest to run but there are certain sections like function calls that run an unknown number of times. Is there a way to use tic and toc around a section of code and get a 'total' execution time duirng a complete simulation run? i.e. the sum of all times it runs or is called
Thanks!

Why not just use the profiler?

There's a tool called profile

help profile

This is designed to do the sort of thing you describe
