bitand
Bit-wise AND
Description
assumes
that C
= bitand(A,B
,assumedtype
)A
and B
are of assumedtype
.
Examples
Truth Table
Create a truth table for the logical AND operation.
A = uint8([0 1; 0 1]); B = uint8([0 0; 1 1]); TTable = bitand(A, B)
TTable = 2x2 uint8 matrix
0 0
0 1
bitand
returns 1 only if both bit-wise inputs are 1.
Negative Values
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 AND of -5 (11111011
) and 6 (00000110
) is 2 (00000010
).
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 = bitand(a,b,'int8')
c = 2
bitget(c,8:-1:1,'int8')
ans = 1×8
0 0 0 0 0 0 1 0
Input Arguments
A,B
— Input values
scalars | vectors | matrices | multidimensional arrays
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

, '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.

— Input values
.NET enumeration objects
Input values, specified as .NET enumeration objects. You must be running a version of Windows® to use .NET enumeration objects as input arguments.
bitand
is an instance method for MATLAB enumeration
objects created from a .NET enumeration.
Output Arguments
C
— Bit-wise AND result
array
Bit-wise AND 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.
objout
— Bit-wise AND result
.NET enumeration object
Bit-wise AND result, returned as a .NET enumeration objects.
