Logical ANDA B A & B 0 0 0 0 1 0 1 0 0 1 1 1 A & B performs a logical AND of arrays A and B 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 both input arrays contain 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. Example: 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 AND operation between A and B is: >> A & B ans = 0 0 0 0 1 1 0 0 0 0 0 0 1 0 1 0 >> Example: If vector x is: x = 0 1 2 3 0 and vector y is: y = 1 2 3 0 0 Then, the AND operation between x and y is: >> x & y ans = 0 1 1 0 0 >> From 'Logical AND' to home From 'Logical AND' to 'Boolean Algebra'
