% PLE "Print Last Error"
%
% ple prints the last error message issued by Matlab, including a complete
% backtrace of the call-sequence of functions that led to the error
% condition. Each line in the backtrace includes M-Filename and line number
% and allows you to open that file on the specified line by simply clicking
% on it with the mouse.
%
% ple is only supported on Matlab version 7 (Release 14 service pack 3) and later.
%
% Usage:
% ple - Print last error, as contained in error structure 'psychlasterror'.
% ple(s) - Print error and backtrace contained in error structure 's'.
%
% Copyright: This implementation of 'ple' is a slightly modified derivate of
% the original public domain implementation of ple.m by Malcolm Wood (the MathWorks).

% The original file can be downloaded from Matlab Central at:
