Bit-wise complement
cmp = bitcmp(A)
cmp = bitcmp(A,assumedtype)
example
cmp = bitcmp(A) returns the bit-wise complement of A.

A
cmp = bitcmp(A,assumedtype) assumes that A is of assumedtype.

A = int8(-11); cmp = bitcmp(A)
cmp = int8 10
You can see the complement operation when the numbers are shown in binary.
original = bitget(A,8:-1:1)
original = 1x8 int8 row vector 1 1 1 1 0 1 0 1
complement = bitget(bitcmp(A),8:-1:1)
complement = 1x8 int8 row vector 0 0 0 0 1 0 1 0
cmp = bitcmp(64,'uint8')
cmp = 191
maxint = intmax('uint8') - 64
maxint = uint8 191
The complement of an unsigned integer is equal to itself subtracted from the maximum integer of its data type.
Input value, specified as a signed integer array, unsigned integer array, or double array.
If A is a double array, and assumedtype is not specified, then MATLAB® treats A as an unsigned 64-bit integer.
If assumedtype is specified, then all elements in A must have integer values within the range of assumedtype.
Data Types: double | int8 | int16 | int32 | int64 | uint8 | uint16 | uint32 | uint64

Assumed data type of A, specified as 'uint64', 'uint32', 'uint16', 'uint8', 'int64', 'int32', 'int16', or 'int8'.
If A is a double array, then assumedtype can specify any valid integer type, but defaults to 'uint64'.
If A is an integer type array, then assumedtype must specify that same integer type.

Bit-wise complement, returned as a signed integer array, unsigned integer array, or double array. cmp is the same size and type as A.
Usage notes and limitations:
The input argument A must be a gpuArray of unsigned integers.
gpuArray
64-bit integers are not supported.
The assumedtype argument is not supported.
