number of cpu cores used in matlab

To play with the number of cores through SBATCH

We mainly do stuff like this

#!/bin/bash

#SBATCH -J job_name

#SBATCH -o job_name.o%j

#SBATCH -t 04:00:00

#SBATCH -N 1 # Asking for 1 Node #SBATCH --ntasks-per-node=20 # Asking for 20 cores

But how can we do this in matlab GUI ?

from the command line.

But if you are wanting to do this for parfor / spmd purposes, then you should edit the 'local' cluster profile.
