%
% Usage
%
% The upper function converts a string to upper case with
% the syntax
%
% y = upper(x)
%
% where x is a string, in which case all of the lower case
% characters in x (defined as the range 'a'-'z') are
% converted to upper case. Alternately, you can call upper
% with a cell array of strings
%
% y = upper(c)
%
% in which case each string in the cell array is converted to upper case.
