bitset

set bit at specified position

Calling Sequence

y = bitset(x,pos)
y = bitset(x,pos,v)

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.

pos :

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. The input pos must be in the range 1,2,...,bitmax where bitmax is the maximum number of bits in x.

v :

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). Default v=1. 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.

Description

Set the bit at specified position.

Examples

// 9 is (01001)_2
// We set the 5th bit to 1, which gives
//      (11001)_2 producing 25
bitset(uint8(9), 5)
expected = 25

// Set the 5th bit of 25 to 0.
bitset(uint8(25), 5, 0)
expected = 9

// The input can be a positive double
bitset(25, 5, 0)
expected = 9
