a problem in parallel computing

Dear all, I need help to do a parallel process for my optimization code. Could you please help me? When I use "parfor", I see this error:

Error using MyCost (line 24) In an assignment A(I) = B, the number of elements in B and I must be the same. Error in @(p)MyCost(p,x0)

Error in Test_ga_Parallel (line 210) parfor i = 1:length(pop)

.... Thanks in advance.

This looks like an error in your MyCost function. Without further details, it's impossible to tell why this error is occurring.

Replace the parfor with a for and make sure it is at least syntactically correct for a basic for loop first.

A syntactically correct for loop doesn't automatically mean a syntactically correct parfor, but a syntactically incorrect for loop does always mean a syntactically incorrect parfor!
