I have a Matlab program which calls a mex function (consuming the largest portion of my program time according to the profiler). I have its C++ code (I generated the mex one on my machine). My problem is that I call this function over 500000 times in my code, and with many runs, it makes my code need over 24 hours to be run. Adding that I need many configurations to be checked, you can imagine the situation I am trapped in. Could anyone suggest how to generate a faster mex file?
@ Peter: I am speechless due to two facts; first you summarised all the issues I went throught to get lesser number of calls, second, your explanation is really very pedagogical. In fact:
1. It is a c++ code called from Matlab, I misused the words.
2. The function in question is the cec13_func found at the cec13 matlab package on the link:

3. In my code, at least the function is called 10000*d times (d=50). so I think I will look, as you recommended, for parallelising the code. Though, I have to manage to make it as independent to iterations as possible.
Thank you again
Hi Amer, I would know if you have found a solution to this problem? I have also the same issue!
Thank you for advance.
