Hi all

I need to use a parfor loop to speed up the code running. However, it reports errors when a statement within this parfor loop (marked in dFC.m, line 45) calls a function which also contains a parfor loop (marked in multilayerNetFunc.m, line 28). I can run them smoothly if I change either of them into 'for-loop'. I have been trying to find the solution by google and looking up the information in this community. But haven't found the right tips.

I really need these two parfor loops stay in position or it will be a week-long process for my computer.

Wish somebody could help me to figure out the solution!

Thanks!

ps: The two scripts have been attached to this post.

Ok~ Thank you very much! I'll see what I can do to upload the runable version. Sorry, I didn't realize this is necessary. The original code needs to call a couple of neuroimaging processing packages. I'll try to replace the input with modelling data and provide the code later. I really hope someone could help me to solve this problem! Thanks!

I have been struggling to make the parfor-loops in dFC.m & multilayerNetFunc.m feasible. But haven't found the solution yet. I have attached the runable version of my code with this post. However, this community doesn't allow to upload packages, I am not sure if without the complete package-(genlouvain:http://netwiki.amath.unc.edu/GenLouvain/GenLouvain) the major script dFC.m still can run smoothly. Nevertheless, I still wish somebody could help me to solve this problem! Thanks!
