Explanation

matlabpool has been removed. Use parpool instead.

parpool creates a pool of workers on the current cluster and connects the MATLAB client. It enables the full functionality of the MATLAB parallel language features including parfor, spmd, and the distributed function.

Suggested Action

Replace occurrences of matlabpool with parpool. In some instances, parpool uses a different syntax than matlabpool. For example:

To start a pool using the current cluster profile, replace matlabpool with parpool.
To query whether a pool exists, replace matlabpool('size') == 0 with isempty(gcp('nocreate')).
To close the current pool, replace matlabpool close or matlabpool('close') with delete(gcp('nocreate')).

For further information, see the parpool and parallel.Pool reference pages.
