xor (MATLAB Function Reference)

Exclusive or

Syntax

C = xor(A,B)

Description

C = xor(A,B) performs an exclusive OR operation on the corresponding elements of arrays A and B. The resulting element C(i,j,...) is logical true (1) if A(i,j,...) or B(i,j,...), but not both, is nonzero.

Examples

Given A = [0 0 pi eps] and B = [0 -2.4 0 1], then

C = xor(A,B)
C =
   0   1   1   0

To see where either A or B has a nonzero element and the other matrix does not,

spy(xor(A,B))
