基于matlab的矩阵论算法，有利于矩阵论初学者使用(Algorithm based on matlab of matrix theory, matrix theory in favor of beginners)

结合具体应用，以2倍抽取为例，简要分析了多相滤波的基本原理及具体实现方法，并附带了matlab代码，从实验结果可以看出多相滤波可以实现与传统FIR滤波相同的功能。(Combine concrete application, take 200 extracts as an example, the synopsis analyzes the radical principle that the polyphase filters and concretely carries out a method, and supplementary matlab code, can discover polyphase to filter as a result to carry out to filter same function with traditional FIR from the experiment.)

用matlab完成高斯回归过程，运用hyperparameter对covriance进行选择(Matlab complete regression with Gaussian process, the use of hyperparameter selection covriance)
