I am running the glmfit inside the parfor loop. I have got the following error, however, when I run it inside for loop, I do not get any error. Is there any inconsistency between parfor and glmfit? I should make it parallel in order to save time.
Warning: Iteration limit reached. > In glmfit at 368 In parallel_function>make_general_channel/channel_general at 914 In remoteParallelFunction at 38

Hi Marzi,
Iteration limit for "glmfit" is set to 100. This is a limitation and you cannot change this value unless you edit the function and change it manually. I work at Mathworks and I have forwarded this to the appropriate product team for consideration.
Meanwhile, you can look at the following MATLAB Answers link which talks about resolving a similar issue by modifying the code for "glmfit":

I hope this helps resolve the issue.
Thanks,
Tushar

Thank you so much for your response and also further consideration.
I was dealing with iteration limit before. However, this case is different. When I run the glmfit regularly, I would not get the iteration limit warning, however, when I run in within parfor I get this warning which is strange since they are supposed to run independently.
