%LASTERR Last error message.
%   LASTERR, by itself, returns a string containing the last
%   error message issued by MATLAB.
%
%   LASTERR('') resets the LASTERR function so that it will
%   return an empty matrix until the next error is encountered.
%   
%   LASTERR is usually used in conjunction with the two 
%   argument form of EVAL: EVAL('try','catch') or the 
%   TRY...CATCH...END statements. The catch action can examine 
%   the LASTERR string to determine the cause of the error and
%   take appropriate action.
%
%   See also EVAL, LASTWARN, ERROR.
