本文包括以下内容：逆滤波，最小二乘方滤波，顺序滤波比较等matlab代码。-This article includes the following: inverse filtering, least squares filtering, comparison of the order of filtering matlab code.

基于稀疏表示的正交最小二乘法，使用的语言是matlab，应用比较广阔，设计信号处理中的信号回归，图像处理的压缩等。-Sparse representation based on orthogonal least squares method, the language used is matlab, relatively broad application, design signal processing signal return, image processing, compression

后向偏最小二乘方法matlab的实现，完全是自己参照公式编的哦-After the partial least squares method matlab realize, is entirely their own formulas reference to the Oh
