matlab isempty

The isempty function in MATLAB checks whether a variable is empty or not. It returns true if the variable is empty and false if it is not empty.

Syntax:

isempty(variable)

Example:

A = [1 2 3];
B = [];
C = '';
D = 'hello';

isempty(A) %returns false
isempty(B) %returns true
isempty(C) %returns true
isempty(D) %returns false
