bitor

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 integers.

Description

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

x, y, z have the same size.

Examples

// '110000' : is the binary representation of 48 
// '100101' : is the binary representation of 37   
// '110101' : is the binary representation for the OR applied to the binary forms 48 and 37 
// so the decimal number corresponding to the OR  applied to binary forms 48 and 37 is : 53
x=48; 
y=37;
z=bitor(x,y)

// Compute the bitwise OR of two matrices of doubles.
x=[12,45]; 
y=[25,49];
z=bitor(x,y)

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

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

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

//  13 is (01101)_2
//  27 is (11011)_2
//  OR is (11111)_2 which is 31.
bitor(uint8(13), uint8(27))
bitor(13, 27)
