MATLAB provides various bit operation functions, such as bitwise AND, OR, NOT, and shift operations.
The following table shows commonly used bitwise operations-
| Function | Description |
|---|---|
| bitand(a, b) | Bitwise AND of integer a and b |
| bitcmp(a) | Bitwise complement of A |
| bitget(a,pos) | Get bit at specified position in integer array a |
| bitor(a, b) | IntegeraAndb'sBitwise OR |
| bitset(a, pos) | Set bit to a specific position pos of a |
| bitshift(a, k) | ReturnOneBy moving leftķBit, equivalent to multiplying by2 ķThe negative value of k corresponds to right shift or division by2 | k | Round to the nearest integer towards negative infinity. Any overflow bits will be truncated. |
| bitxor(a, b) | Bitwise XOR of Integer a and b |
| swapbytes | Swap Byte Order |
Create a script file and enter 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 running the file, it displays the following result
c = 12 c = 61 c = 49 c = 240 c = 15
