19 Nov 2008 untexlabel Build a string which used with a TeX interpreter shows exactly the string as it is ... Author: Giuseppe Ridinò

This utility works as advertised - as mentioned, only a select few text objects have the "Interpreter" property available, and this solves the case where that property is not available - I used it to properly display the underscores in a "waitbar" message. Nice work!

How does quant() work?
03 Aug 2011 Two's Complement Compute the two's complement value of an unsigned integer Author: Chad Webb Zelazowski, Przemyslaw

Similar to Jeremy, I don't see the functionality of the code if the input must be unsigned integer. Isn't the two's component mainly used to deal with negative numbers?
10 Dec 2010 Two's Complement Compute the two's complement value of an unsigned integer Author: Chad Webb Ghannoum, Anthony

Hello, I hope you don't mind, I modified it a bit to handle matrices, and overflows. Cheers !

function value = TwosComplement(x, numBits)
if ~isnumeric(x) || ~isnumeric(numBits) || nargin ~= 2
    error (' Function requires two numeric input arguments');
end
if numBits < 2
    error ('numBits should be at least 2 for a Twos Complement representation');
end
% Create MSB matrix (Shift right, and truncate remaining bits if any)
msb = mod(bitshift(x, -(numBits - 1) ),2);
% Calculate all positive values (Truncate the input)
value = mod(x,2^(numBits - 1));
% Calculate all negative values (Invert and add 1)
neg = -1 * ( bitcmp(mod(x, 2^(numBits -1)), numBits -1) + 1 );
% Use MSB matrix as a mask to choose either the positive or negative value
value(msb ~= 0)= neg(msb ~= 0);
end

um...the 2's complement of an unsigned value is just the dec2bin function...what's the point if it's unsigned?

The function quant(.,.) is missing...
