not, ~

Find logical NOT

Syntax

~A
not(A)

Description

~A performs a logical NOT of input array A, and returns an array containing elements set to either logical 1 (true) or logical 0 (false). An element of the output array is set to 1 if the input array contains a zero value element at that same array location. Otherwise, that element is set to 0.

The input of the expression can be an array or can be a scalar value. If the input is an array, then the output is an array of the same dimensions. If the input is scalar, then the output is scalar.

not(A) is called for the syntax ~A when A is an object.

Examples

If matrix A is

     0    29     0    36     0
    23    34    35     0    39
     0    24    31    27     0
     0    29     0     0    34

then

~A
ans =
     1     0     1     0     1
     0     0     0     1     0
     1     0     0     0     1
     1     0     1     1     0
