Try
maxNumCompThreads(10);

LASTN = maxNumCompThreads(N)
sets the maximum number of computational threads to N, and returns the previous maximum number of computational threads, LASTN. N in your case is 10.
You can also use
LASTN = maxNumCompThreads('automatic')
which will set the maximum number of computational threads to the most desirable number according to MATLAB.
