引入较好的预处理子，加快共轭梯度法的收敛速度(The introduction of better preconditioners, conjugate gradient method to speed up the convergence rate)

The Program helps to remove numbers at the beginning of a Matlab script. It is very useful when one has copied a code from a text into Matlab environment and eager to tun it immediately.

　　利用matlab程序实现对一维信号进行连续小波变换，进而在程序的编辑过程理解一位连续小波变换的小波系数矩阵的含义。 　　同时通过对预算的到的小波系数矩阵进行分析解释，得到原始信号的频谱分布以及了解小波系数在尺度和位移两个分量上的意义。(Matlab program to achieve continuous wavelet transform of one-dimensional signal, and then in the editing process of the program to understand the meaning of a continuous wavelet transform coefficient matrix. Analysis to explain the budget to the wavelet coefficients matrix, the spectral distribution of the original signal, and understand the significance of the wavelet coefficients on the two components of scale and displacement.)

功率电子领域matlab仿真文件，已经验证过，程序运行正常(Power electronics field matlab simulation file, has already been verified, the normal operating procedures)

arff parser for reading and writing arff file

ofdm的一种信道估计准则：最大似然信道估计准则(ofdm channel estimation as a criterion: maximum-likelihood channel estimation criteria)

实现快速傅里叶变换函数的matlab程序，以2D作为基来写的(Fast Fourier transform function matlab program to 2D as a base to write)

mimoZF和 mmse 的 预编码 matlab code 源码(Precoding matlab code source for mimoZF and MMSE)
