研一，学校开了数值分析这门课，而且要求用matlab进行上机试验，就写数值分析常微分方程的7个MATLAB算法，都是能够套用的M文件。还有我自己的上机作业。很不错的，能参考。要想要其它章的算法，我都已经上传了。(Kenichi, the school opened the numerical analysis of the course, but also carried out on machines with matlab test, on the numerical analysis of ordinary differential equations to write the seven MATLAB algorithms, are able to apply the M-file. Also on my own machine operation. Very good, can draw on. To want the algorithm to other chapters, I have already uploaded.)

说明：  浅谈加权最小二乘法及其残差图及其详细的讨论(On the weighted least squares method and the residual map and detailed discussions)

本程序为一个实现MIMO-OFDM信道估计的程序，程序中采用的为2*2系统，可以换成其他系统(procedures for the realization of a MIMO-OFDM channel estimation procedures, procedures for the use of 2* 2 system, could be replaced with other systems)
