Usage
The isempty function returns a boolean that indicates if the
argument variable is empty or not. The general syntax for
its use is
y = isempty(x).
Examples
Here are some examples of the isempty function
--> a = []
a =
[]
--> isempty(a)
ans =
1
--> b = 1:3
b =
1 2 3
--> isempty(b)
ans =
0
Note that if the variable is not defined, isempty does not
return true.
--> clear x
--> isempty(x)
Error: Undefined function or variable x
