30 Jan 2012 Two's Complement for MATLAB Calculating two's complement for a decimal number. Author: Tal Levinger duanra

 if N is the number of bit
and b an array of integer to convert in signed this operation could be faster

       if( b(n) > (2^(N-1)-1))
            b(n)=b(n)-2^N;
        else
            b(n)=b(n);
        end;
13 Nov 2010 Two's Complement for MATLAB Calculating two's complement for a decimal number. Author: Tal Levinger Naseri, Hassan

function value = dec2tc(dec, N)
value = dec2bin(mod((dec),2^N),N);
end

function value = tc2dec(bin,N)
val = bin2dec(bin);
y = sign(2^(N-1)-val)*(2^(N-1)-abs(2^(N-1)-val));
if ((y == 0) && (val ~= 0))
  value = -val;
else
    value = y;
end
end
07 Sep 2007 Two's Complement for MATLAB Calculating two's complement for a decimal number. Author: Tal Levinger Baur, Rafael

there is a easier way to calculate the two's complement:
twos_comp = dec2bin(mod((value),2^bits),bits);

look at a those two's complement circles then you will see why it works.
07 May 2007 Two's Complement for MATLAB Calculating two's complement for a decimal number. Author: Tal Levinger Webb, Chad

Handy for 16 bit numbers, but not anything else. It even takes an input for what appears to be the number of bits (i.e. other than 16), but never utilizes it. Good start on a function that could be far more useful.
