%LASTWARN Last warning message.
%   LASTWARN, by itself, returns a string containing the last
%   warning message issued by MATLAB.
%
%   LASTWARN('') resets the LASTWARN function so that it will
%   return an empty string matrix until the next warning is encountered.
%   
%   LASTWARN('string') sets the last warning message to 'string'.
%   The last warning message is updated irrespective of whether warning 
%   is on or off.
