绝对经典,老外制作的功能强大的matlab实现PLS_TOOBOX

% MATLAB7TO5: In order to load results generated using Matlab 7 on 
%	earlier versions of Matlab, a special Matlab 7 switch must 
%	be included during the saving process. Since such a switch
%	is not coded in the package, this small program is used to
%	covert the .mat files generated from Matlab 7 to be loaded
%	on earlier versions of Matlab that are above Matlab 5.
%
% Usage:	matlab7to5('abc.mat') or simply:
%		matlab7to5('*.mat')
%
