Hi everyone,

I cannot open matlabpool local. The error message is

    Error using parallel.internal.pool.InteractiveClient/start (line 326)
    Failed to start pool.
        Error using parallel.Job/submit (line 304)
        All dimension arguments must be greater than zero

Could anyone tell me what does this mean? How can I fix it? Thanks a lot!

best, Rui

Solved it. It was firewall, as someone mentioned somewhere. On Windows go to: Control Panel\System and Security\Windows Firewall\Allowed applications and allow :

Matlab 2013b (my version)
mpiexec
smpd

If you can not find them on the list, browse to Matlab installation folder usualy: C:\Program Files\MATLAB\R2013b\bin\win64 and allow mpiexec.exe and smpd.exe.

Also does not work for me. I've added the rules, and have tried disabling the firewall entirely. I still get the same error.

i confirm , it's a firewall problem ! not only is it about Windows firewall but also antivirus firewall . matlab need to be allowed by both firewall (windows and avast for me).
