islogical (MATLAB Functions)

MATLAB Function Reference

islogical

Determine if input is logical array

Syntax

```
tf = islogical(A)
```

Description

tf = islogical(A) returns logical 1 (true) if A is a logical array and logical 0 (false) otherwise.

Examples

Given the following cell array,

C{1,1} = pi;                 % double
C{1,2} = 1;                  % double
C{1,3} = ispc;               % logical
C{1,4} = magic(3)            % double array

C = 
    [3.1416]    [1]    [1]    [3x3 double]

islogical shows that only C{1,3} is a logical array.

for k = 1:4
x(k) = islogical(C{1,k});
end

x
x =
     0     0     1     0
