physical and logical cores

Hello

Please, how I can use the four physical cores.

feature('numCores');
MATLAB detected: 4 physical cores.
MATLAB detected: 4 logical cores.
MATLAB was assigned: 4 logical cores by the OS.
MATLAB is using: 4 logical cores.

It's using only logical cores, not physical cores.

MATLAB typically will use multiple cores automatically for functions that are programmed to use them. E.g., large matrix multiplies will use multiple cores in the background without the user needing to specify that multiple cores should be used. Is there something specific that you are doing that you think should be using multiple cores but isn't?

but why it uses just 4 logical cores
