numlabs

Total number of workers operating in parallel on current job

Syntax

n = numlabs


Description

n = numlabs returns the total number of workers currently operating on the current job. This value is the maximum value that can be used with labSend and labReceive.

Tips

In an spmd block, numlabs on each worker returns the parallel pool size.

However, inside a parfor-loop, numlabs always returns a value of 1.
