How can I save the variables x and fval when using [x,fval] = fmincon() in a parfor?

I get the following error:

An UndefinedFunction error was thrown on the workers for 'x'. This might be because the file containing 'x' is not accessible on the workers. Use addAttachedFiles(pool, files) to specify the required files to be attached. See the documentation for 'parallel.Pool/addAttachedFiles' for more details.

I still get the error message if I try to save the results x{i} to another variable outside the parfor loop. Any suggestions how to do this?

parfor K = ....
 [x{K}, fval{K}] = fmincon(.....)
end

That works perfectly. Thank you!
