%
% Usage
%
% Converts an integer to a binary string. The syntax for its
% use is
%
% y = dec2bin(x,n)
%
% where x is the positive integer, and n is the number of
% bits to use in the representation. Alternately, if you leave
% n unspecified,
%
% y = dec2bin(x)
%
% the minimum number of bits needed to represent x are used.
% If x is a vector, then the resulting y is a character
% matrix.
