BITXOR BITXOR Bitwise Boolean Exclusive-Or (XOR) Operation Usage Performs a bitwise binary xor operation on the two arguments and returns the result. The syntax for its use is y = bitxor(a,b) where a and b are unsigned integer arrays. The xor operation is performed using 32 bit unsigned intermediates. Note that if a or b is a scalar, then each element of the other array is xored with that scalar. Otherwise the two arrays must match in size.
