bitset - Set bit at certain position

Syntax

c = bitset(a, bit)
c = bitset(a, bit, v)

Description

c = bitset(a, bit) sets bit position bit in a to 1 (on).

c = bitset(a, bit, v) sets bit position bit in a to v. v must have a value 0 (off) or 1 (on). Any value v other than 0 is automatically set to 1.

bit must be a number between 1 and the word length of a, inclusive. If a has a signed numerictype, the bit representation of the stored integer is in two's complement representation.

bitset only supports fi objects with fixed-point data types. a can be a scalar fi object or a vector fi object. bit and v can be scalars or vectors.

Example

This example shows how to set a bit of a fi object. Consider the following unsigned fixed-point fi object with a value of 5, word length 4, and fraction length 0:

a = fi(5,0,4,0);
disp(bin(a))

0101

Set the bit at position 2 to 1:

c = bitset(a,2,1);
disp(bin(c))

0111
