2's compliment in matlab

[singhji0000]

Hello all,

i needed to find the 2's compliment. I am getting result from comparator in form of 0 and 1 and the result are getting stored in array
eg. x = [1 0 1 1 0 0 1 1] from LSB to MSB

how can i find the 2's compliment for this result stored in the array using matlab program?

thanks

Here's your code:
*******************

clc
clear
% x = your array
x = [1 0 1 1 0 0 1 1];
for i=1:8               
    if(x(i))
       y(i) = 0;
    else y(i) = 1;
    end
end
% y contains inverted number
c = y;
if(~c(1))
    c(1) = 1;
else
    for i=1:8
        if(~c(i))
            c(i) = 1;
            c(1:i-1) = 0;
            break;
        end
    end
end
% c contains 2's complement
clear i;

this is just one simple way of doing it.
