isvalid - Class: qrandstream

Test handle validity

Syntax

tf = isvalid(h)

Description

tf = isvalid(h) performs an element-wise check for validity on the handle elements of h. The result is a logical array of the same dimensions as h, where each element is the element-wise validity result.

A handle is invalid if it has been deleted or if it is an element of a handle array and has not yet been initialized.
