Empty Array (User Guide)

Introduction
This VI is used to determine if an n-dimension array is empty array. The polymorphic instances allow this VI to be used with any LabVIEW data type that can be made into an array. Several polymorphic instances exist to explicitly handle most common LabVIEW data types, and a variant version exists to handle all other LabVIEW data types.

Typical Use Cases
Detecting an Empty Array



Polymorphic Instances



Notice the coercion dot to represent the coercion of the 3D array to a variant array (since there are no polymorphic instances for 3D arrays).

Polymorphic Instances
The polymorphic VI contains array versions for most common LabVIEW data types, natively. All other array types are handled by converting them to a variant before checking the array size.
