iscategorical

Determine whether input is categorical array

Syntax

tf = iscategorical(A)

Description

tf = iscategorical(A) returns logical 1 (true) if A is a categorical array. Otherwise, iscategorical returns logical 0 (false).

Examples

Determine Whether Workspace Variable Is Categorical Array

Create a workspace variable, A.

A = categorical({'red' 'green' 'violet'; 'orange' 'red' 'yellow'})

A = 2x3 categorical
     red         green      violet 
     orange      red        yellow 

Verify that the workspace variable, A, is a categorical array.

tf = iscategorical(A)

tf = logical
   1

A is a 2-by-3 categorical array.

Input Arguments
