Attached is the profiling results of my code, where the most time-consuming lines are those from build-in functions(e.g., find, max, min,...). As my code cannot be vectorized or run in parallel, I am wondering how to speed up the code? If gpu computing or convert to mex file help for this case?

Thank you very much.

It doesn't look as though the problem is the speed of execution of those functions, so much as the number of times they are called. You should have a go at removing your loops by vectorizing your code.
