how to create function half adder in matlab

halfAdder : it accepts 2 bits as input arguments. It adds these bits and returns 2 bits as output arguments: the sum and the output carry

[James Tursa]

What is this for? How are the bits passed in? I.e., what are the variable classes involved?

[Roger Stafford]

If the input bits are numeric scalars or logical values, b1 and b2, then the sum bit, 's', would be:

s = b1 xor b2;

or else

s = (b1&~b2) | (~b1&b2);

These are equivalent. That leaves you with the 'carry' bit to figure out.
