isind

Return true for an indexed image

Syntax

• flag = isind(A)
  

Description

flag = isind(A) returns 1 if A is an indexed image and 0 otherwise.

isind uses these criteria to determine if A is an indexed image:

• If A is of class double, all values in A must be integers greater than or equal to 1, and the number of dimensions of A must be 2.
• If A is of class uint8 or uint16, the number of dimensions of A must be 2.

Note    A four-dimensional array that contains multiple indexed images returns 0, not 1.

Class Support

A can be of class logical, uint8, uint16, or double.
