# MATLAB - Bitwise Operations

MATLAB provides various functions for bit-wise operations like 'bitwise and', 'bitwise or' and 'bitwise not' operations, shift operation, etc.

The following table shows the commonly used bitwise operations −

Function Purpose
bitand(a, b) Bit-wise AND of integers a and b
bitcmp(a) Bit-wise complement of a
bitget(a,pos) Get bit at specified position pos, in the integer array a
bitor(a, b) Bit-wise OR of integers a and b
bitset(a, pos) Set bit at specific location pos of a
bitshift(a, k) Returns a shifted to the left by k bits, equivalent to multiplying by 2k. Negative values of k correspond to shifting bits right or dividing by 2|k| and rounding to the nearest integer towards negative infinite. Any overflow bits are truncated.
bitxor(a, b) Bit-wise XOR of integers a and b
swapbytes Swap byte ordering

## Example

Create a script file and type the following code −

```a = 60;               % 60 = 0011 1100
b = 13;               % 13 = 0000 1101
c = bitand(a, b)      % 12 = 0000 1100
c = bitor(a, b)       % 61 = 0011 1101
c = bitxor(a, b)      % 49 = 0011 0001
c = bitshift(a, 2)    % 240 = 1111 0000 */
c = bitshift(a,-2)    % 15 = 0000 1111 */
```

When you run the file, it displays the following result −

```c =  12
c =  61
c =  49
c =  240
c =  15
```
