Syntax

• out = isvalid(obj)
  

Description

out = isvalid(obj) returns a logical array out that contains a 1 where the elements of obj are image acquisition objects associated with hardware and a 0 where the elements of obj are image acquisition objects not associated with hardware.

An object is an invalid image acquisition object when it is no longer associated with any hardware. If this is the case, obj should be cleared from the workspace.
