`canUseParallelPool`

Tells whether a parallel pool can be used.

Category: Programming > Programming Utilities

Syntax

tf = canUseParallelPool

Returns true if parallel features such as parfor can run on a pool, false otherwise.

Description

Use it to decide between a parallel and a serial implementation without triggering an error or starting a pool. The result describes availability only; it does not say whether a pool is currently open.

Output arguments

tf: Logical scalar.

Example

Serial fallback

if canUseParallelPool
    disp('parallel pool available')
else
    disp('running serially')
end

Output

running serially

Notes

MatLivre has no parallel pool, so canUseParallelPool always returns false.
