# bitcmp

bitwise complement

### Calling Sequence

y = bitcmp(x,n)

### 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.

- n :
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). The input

`n`

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

Given an unsigned integer `x`

, this function returns the unsigned integer
which is the integer corresponding to the complementary of the binary
form of `x`

.

The integer `n`

sets the maximum number of bits.

If the bits number of the `x`

binary representation is less than the
bitmax number (8,16 or 32) then the bits '1' are added to the
complementary in order to have bitmax number (8, 16 or 32) for the
complementary.

### Examples

// 13 is (1101)_2 // We insert zeros in the begining to get a 8-bit number: // (00001101)_2 // The 8-bits complement is then (11110010)_2 // which is 242 bitcmp(13,8) expected = 242 // The input argument can be an unsigned int bitcmp(uint8(99),8) expected = 156
