I have a Matlab code which uses a function called foo.
This function has been written in C (foo.c being the original file) and compiled in order to generate a Matlab library called foo.mexa64.
The code runs successfully.
My question is: Is there any way to debug this function foo within Matlab?
I need to know, step by step, some local value inside foo function!
Not it's not possible using only MATLAB.
I haven't tried, but it is possible using general purpose c/c++ debuggers. Mathworks has a pretty detailed documentation on how to do this:
