MATLAB Functions

Detect an object of a given class

K = isa(obj,'class_name')

K = isa(obj,'class_name')

returns logical true (1) if obj is of class (or a subclass of) class_name, and logical false (0) otherwise.

The argument class_name is the name of a user-defined or pre-defined class of objects. Predefined MATLAB classes include


`cell`	Multidimensional cell array
`double`	Multidimensional double precision array
`sparse`	Two-dimensional real (or complex) sparse array
`char`	Array of alphanumeric characters
`struct`	Structure
`'class_name'`	User-defined object class

isa(rand(3,4),'double') returns 1.
