Query the Class Name

To determine the class of an array, use the class function:

a = [2,5,7,11];

class(a)

ans =

double

str = 'Character array';

class(str)

ans =

char

Test for Array Class

The isa function enables you to test for a specific class or a category of numeric class

(numeric, float, integer):

a = [2,5,7,11];

isa(a,'double')

ans =

1

Floating-point values (single and double precision values):

isa(a,'float')

ans =

1
