horzline.m

一些偏最小二乘法（PLS)间隔偏最小二乘(siPLS)联合区间偏最小二乘等的建模代码。

function horzline(place,color)
%  horzline puts a horizontal line at a given value(s)
%  hline(1.4,'--b'); plots a horizontal dashed
%  blue line at place = 1.4. If no input arguments are given,
%  hline will draw a horizontal green line at 0.

%  horzline(place,color)

if nargin == 0
  place = 0;
