islogical

Determine if an array is a logical array

Usage

islogical(A)

• A should be an array.
• It returns logical 1 if A is a logical array, and logical 0 if otherwise.
• It returns logical 1 if A is empty.

Example

• 1 is not a logical array since it is a double. The characters 'a' is not a logical array, obviously. The comparison 1 < 2 gives a logical array since the result of a comparison operator is a logical value.

Input

islogical(1)
islogical('a')
islogical(1 < 2)

Output

ans = 
0

ans = 
0

ans = 
1
