I am assuming that you want to use PCT functions using numerous workers on your local machine. You can check all these properties by below mentioned steps.
1. Click on Home tab on your MATLAB 2. Click on Parallel, a drop down list will appear 3. Go to parallel preferences to setup number of workers. 4. Click on Manage Cluster Profile and validate local profile.
Try to run below mentioned command.
>>parpool(4) % to create pool of 4 workers And, check if it works fine. If it works fine then you can your matlab code using these 4 workers.
