pctRunOnAll - Run command on client and all workers in matlabpool

Syntax

Description

pctRunOnAll command runs the specified command on all the workers of the matlabpool as well as the client, and prints any command-line output back to the client Command Window. The specified command runs in the base workspace of the workers and does not have any return variables. This is useful if there are setup changes that need to be performed on all the labs and the client.

Note   If you use pctRunOnAll to run a command such as addpath in a mixed-platform environment, it can generate a warning on the client while executing properly on the labs. For example, if your labs are all running on Linux operating systems and your client is running on a Microsoft Windows operating system, an addpath argument with Linux-based paths will warn on the Windows-based client.

Examples

Clear all loaded functions on all labs:

pctRunOnAll clear functions

Change the directory on all workers to the project directory:

pctRunOnAll cd /opt/projects/c1456

Add some directories to the paths of all the labs:

pctRunOnAll addpath({'/usr/share/path1' '/usr/share/path2'})
