Logical NOTIn MATLAB, ~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). This is the truth table and the representation of a NOT Gate as it's represented in digital electronics.
An element of the output array is set to 1 if A contains a zero value element at that same array location. Otherwise, that element is set to 0. Example 1: If matrix A is: A = 0 0 1 1 1 1 0 0 0 0 0 0 1 1 1 1 Then, the NOT A is produced: >> ~A ans = 1 1 0 0 0 0 1 1 1 1 1 1 0 0 0 0 Example 2: If vector x is: x = 0 1 2 -3 0 Then, the NOT x is produced: >> ~x ans = 1 0 0 0 1 From 'Logical NOT' to home From 'Logical NOT' to 'Boolean Algebra'
