Logical OR - (logic OR gate)A | B performs a logical OR of arrays A and B and returns an array containing elements set to either logical 1 (TRUE) or logical 0 (FALSE). Sometimes, this operation is considered an 'addition' in terms of electronic gates. This is the truth table and the representation of an OR Gate as it's seen in digital electronics.
An element of the output array is set to 1 if either input array contains a non-zero element at that same array location. Otherwise, that element is set to 0. A and B must have the same dimensions unless one is a scalar. This is a simple example on how you can code it in Matlab. Example 1: If matrix A is: A = 0 0 1 1 1 1 0 0 0 0 0 0 1 1 1 1 and matrix B is: B = 0 0 0 0 1 1 1 1 0 1 0 1 1 0 1 0 Then, the OR operation between A and B is: >> A | B ans = 0 0 1 1 1 1 1 1 0 1 0 1 1 1 1 1 >> Example 2: If vector x is: x = 0 1 2 3 0 and vector y is: y = 1 2 3 0 0 Then, the OR operation between x and y is: >> x | y ans = 1 1 1 1 0 From 'Logical OR' to home From 'Logical OR' to 'Boolean Algebra'
