## 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
