bitxor

Parameters

x :

a m-by-n matrix of doubles or a m1-by-m2-by-...-by-mm hypermatrix of doubles or a m-by-n matrix of unsigned integers (uint8, uint16 or uint32). Must contain positive integer values.

y :

a m-by-n matrix of doubles or a m1-by-m2-by-...-by-mm hypermatrix of doubles or a m-by-n matrix of unsigned integers (uint8, uint16 or uint32). Must contain positive integer values.

z :

a m-by-n matrix of doubles or a m1-by-m2-by-...-by-mm hypermatrix of doubles or a m-by-n matrix of unsigned integers.

Description

Given x, y two positive integers, this function returns the decimal number whose the binary form is the XOR of the binary representations of x and y.

Examples

// Compute the bitwise XOR of two matrices of doubles.
x = [0 1 0 1];
y = [0 0 1 1];
z = bitxor(x, y)
expected = [0 1 1 1];

// Compute the bitwise XOR of two matrices of integers.
x = uint8([0 1 0 1]);
y = uint8([0 0 1 1]);
z = bitxor(x, y)

// The types of x and y cannot be mixed (error).
x = [0 1 0 1];
y = uint8([0 0 1 1]);
z = bitxor(x, y)

//  13 is (01101)_2
//  27 is (11011)_2
// XOR is (10110)_2 which is 22.
bitxor(uint8(13), uint8(27))
bitxor(13, 27)
