改进了BIHT l2 中的观测矩阵，实验结果证明，误差更小了(change BIHT l2 ，perform better)

是一片外文文献，关于稀疏表示的，与大家分享，欢迎下载(Is a foreign literature on sparse representation, to share with you, welcome to download)

说明：  针对MATLAB的优化功能，本人特别整理了MATLAB常用的优化工具箱代码(MATLAB function for optimization, I used the special finishing of the optimization toolbox of MATLAB code)

这是一个决策树的matlab实现，已经测试通过(This is a matlab implementation of decision tree, have the test pass)

Tests the switch statement.

实现对给定的数据服的拟合优度的检验，内有详细程序说明(To achieve a given data service goodness of fit test, with detailed description of the procedures)

gives the bldc motor simulation with the dtc control.
