vertcat.m

模式识别 MATLAB 的工具箱,比较实用,包括SVM,ICA,PCA,NN等等模式识别算法.

function w = vertcat(varargin)
%disp('mappping-vertcat')
w = varargin{1}; start = 2;
if nargin == 1, return; end
if isempty(w)
	w = varargin{2}; start = 3;
	if nargin == 2, return; end
end

	if cw == 1 & size(w.l,1) == 2
		w.c = 2; cw = 2;
	end
	w = mapping('parallel',w,w.l,kw,cw,1);
	w.d = {w.d};
end
isc = ischar(w.l);

	end
