LOGICAL Convert to Logical

Section: Type Conversion Functions

Usage

Converts the argument to a logical array. The syntax for its use is 
   y = logical(x)

where x is an n-dimensional numerical array. Any nonzero element maps to a logical 1.

Example

Here we convert an integer array to logical: 
--> logical([1,2,3,0,0,0,5,2,2])

ans = 
 1 1 1 0 0 0 1 1 1

The same example with double precision values: 

--> logical([pi,pi,0,e,0,-1])

ans = 
 1 1 0 1 0 1
