I have defined a zero matrix which its elements is determined inside a PARFOR loop. I want to stop running of the program and obtain the values calculated until now. Is that a way to obtain those elements from inside of the PARFOR loop?

For debugging, it is generally better to start with for instead of parfor, because precisely what you're trying to do here is difficult. I don't know if it is impossible, but that wouldn't surprise me.

You can probably add a temporary instruction to save the matrix to file given certain conditions, but unless you have a problem that only occurs in a parfor loop and not in a for loop it is not really worth the effort.

I guess you could also just spew its contents out to command window when some condition or other is met, although creating such a condition is trickier in a parfor loop than a for loop since things are not necessarily happening in contiguous order.
