bitxor
Bit-wise XOR
Description
Examples
Create a truth table for the logical XOR operation.
A = uint8([0 1; 0 1]); B = uint8([0 0; 1 1]); TTable = bitxor(A, B)
TTable = 2×2 uint8 matrix
0 1
1 0
bitxor
returns 0 if both bit-wise inputs are equal.
MATLAB® encodes negative integers using two's complement. For example, to find the two's complement representation of -5, you take the bit pattern of the positive version of the number (00000101
), swap each bit (11111010
), and then add 1 to the result (11111011
).
Therefore, the bit-wise XOR of -5 (11111011
) and 6 (00000110
) is -3 (11111101
).
a = -5;
bitget(a,8:-1:1,'int8')
ans = 1×8
1 1 1 1 1 0 1 1
b = 6;
bitget(b,8:-1:1,'int8')
ans = 1×8
0 0 0 0 0 1 1 0
c = bitxor(a,b,'int8')
c = -3
bitget(c,8:-1:1,'int8')
ans = 1×8
1 1 1 1 1 1 0 1
Input Arguments
Input values, specified as scalars, vectors, matrices, or multidimensional
arrays. Inputs A
and B
must
either be the same size or have sizes that are compatible (for example, A
is
an M
-by-N
matrix and B
is
a scalar or 1
-by-N
row vector).
For more information, see Compatible Array Sizes for Basic Operations. A
and B
also
must be the same data type unless one is a scalar double.
If
A
andB
are double arrays, andassumedtype
is not specified, then MATLAB® treatsA
andB
as unsigned 64-bit integers.If
assumedtype
is specified, then all elements inA
andB
must have integer values within the range ofassumedtype
.
Data Types: double
| logical
| int8
| int16
| int32
| int64
| uint8
| uint16
| uint32
| uint64
Assumed data type of A
and B
,
specified as 'uint64'
, 'uint32'
, 'uint16'
, 'uint8'
, 'int64'
, 'int32'
, 'int16'
,
or 'int8'
.
If
A
andB
are double arrays, thenassumedtype
can specify any valid integer type, but defaults to'uint64'
.If
A
andB
are integer type arrays, thenassumedtype
must specify that same integer type.
Data Types: char
| string
Input values, specified as .NET enumeration objects. You must be running a version of Windows® to use .NET enumeration objects as input arguments.
bitxor
is an instance method for MATLAB enumeration
objects created from a .NET enumeration.
Output Arguments
Bit-wise XOR result, returned as an array. C
is
the same data type as A
and B
.
If either
A
orB
is a scalar double, and the other is an integer type, thenC
is the integer type.
Bit-wise XOR result, returned as a .NET enumeration objects.

The bitxor
function
supports GPU array input with these usage notes and limitations:
Both inputs can be unsigned integer arrays, or one input can be an unsigned integer array and the other input can be a scalar double.
64-bit integers are not supported.
The
assumedtype
argument is not supported.
For more information, see Run MATLAB Functions on a GPU (Parallel Computing Toolbox).
Usage notes and limitations:
The
assumedtype
argument is not supported.
