bitand
bitwise AND
Calling Sequence
z = bitand(x,y)
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).
- 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 AND of the binary representations of x and y.
x
, y
, z
have the same size.
Examples
// '1010110' : is the binary representation of 86 // '1011011' : is the binary representation of 91 // '1010010' : is the binary representation for the AND of binary representation 86 and 91 // so the decimal number corresponding to the AND applied to binary forms 86 and 91 is : 82 x=86; y=91; z=bitand(x,y) // Compute the bitwise AND of two matrices of doubles. x=[12,45]; y=[25,49]; z=bitand(x,y) // Compute the bitwise AND of two matrices of doubles. x = [0 1 0 1]; y = [0 0 1 1]; z = bitand(x, y) expected = [0 0 0 1]; // Compute the bitwise AND of two matrices of integers. x = uint8([0 1 0 1]); y = uint8([0 0 1 1]); z = bitand(x, y) // The types of x and y cannot be mixed (error). x = [0 1 0 1]; y = uint8([0 0 1 1]); z = bitand(x, y) // 13 is (01101)_2 // 27 is (11011)_2 // AND is (01001)_2 which is 9. bitand(uint8(13), uint8(27)) bitand(13, 27)
