Different Results when calling feval

Hi all,

When I call my function in a parfor loop via feval it just returns zeros.

The same setting but without parfor returns the actual and correct results of the function. I just checked it going through the built-in genetic algorithm functions step by step when 'UseParallel' is set as true (whilst 'UseVectorized' already set as false).

What am I missing? How does the structure of my handled function affect the result? Unfortunately, I can not paste here the body of the function.

Thanks in advance!

It is impossible to guess, why the code does, what it does, without seeing it. If you cannot show us the code, helping is based on guessing.

Global variables and persistent variables are not copied into the clients of parfor workers.
