利用MATLAB软件实现偏最小二乘回归方程模型-use the soft of the MATLAB to calculate the partial least-squares regression

单因变量偏最小二乘回归matlab程序 程序尚不完善，固定提取了3个主成分，没有做寻求最佳主成分个数；没有做交叉有效性检验 -Single dependent variable and partial least squares regression matlab The program is not perfect, the fixed extract 3 principal components, do not seek the best number of principa

偏最小二乘回归的MATLAB实现，根据其中注释使用即可，可当作学习PLS的材料。(MATLAB implementation of partial least squares regression)
