maxNumCompThreads

Control maximum number of computational threads

    Note:   maxNumCompThreads will be removed in a future version. You can set the -singleCompThread option when starting MATLAB® to limit MATLAB to a single computational thread. By default, MATLAB makes use of the multithreading capabilities of the computer on which it is running.

Syntax

N = maxNumCompThreads
LASTN = maxNumCompThreads(N)
LASTN = maxNumCompThreads('automatic')

Description

N = maxNumCompThreads returns the current maximum number of computational threads N.

LASTN = maxNumCompThreads(N) sets the maximum number of computational threads to N, and returns the previous maximum number of computational threads, LASTN.

LASTN = maxNumCompThreads('automatic') sets the maximum number of computational threads using what the MATLAB software determines to be the most desirable. It additionally returns the previous maximum number of computational threads, LASTN.

Currently, the maximum number of computational threads is equal to the number of computational cores on your machine.

    Note   Setting the maximum number of computational threads using maxNumCompThreads does not propagate to your next MATLAB session.
