I'm having a memory leakage somewhere in my code that I can't find. I have a matlab code that uses objects to read different files, process them and add the results to a database. In pseudocode, let's say:
The "processor" object uses parfor inside. The pararllel pool is being created and deleted inside the "processor" object in each iteration. I'm running this loop over the same file several time and monitoring the ram usage (using "memory" command in windows, and monitoring the "MemAvailableAllArrays" field), and also the size of each object (using the "GetSize" function). The database is a huge matrix where I accumulate the results.
The MemAvailableAllArrays is decreasing from iteration to iteration. I thought that maybe one of the objects might be concatenating some vectors by mistake, increasing thus its size, but all objects sizes remain contant for iteration to iteration.
Any advise on how to find / solve where this memory "leak" is and/or how to solve it?
Edit: I tried with Matlab 2016b and 2020b, and same issue.
