# 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```
