My parallel computing code (R2013b) is very slow
显示 更早的评论
Hi! I am trying to use parallel computing and parfor loops with my R2013b MatLab version. I can already use parfor cycles but they are slow, a bit slower that the corresponding for cycle. Why is that? When I write parpool in the command window, I get: undefined function or variable 'parpool' Thank you for your help, Sebastiano.

If you are using an earlier of MATLAB, replace parpool with matlabpool
Take a look at the release notes for 13b:
