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
