butterworth滤波器，实现高通低通带通的butterworth滤波器

四叉树编码和测试的RGB图像解码方案，在matlab7.0中验证可行(Quadtree coding and testing of the RGB image decoding program, verify possible in matlab7.0)

说明：  matlab平台上实现FXLMS算法的例程(The routine of FXLMS algorithm on MATLAB platform)

matlab高级讲义，其中包括各个实用例子的编程代码(matlab senior notes, including various practical examples of programming code)

关于图像的灰度处理，翻转，很不错的源码还有界面。(On the gray image processing, flip, very good source are the interface.)

基于维特比译码算法的BPSK解调方式，survivor_state是一个矩阵，它显示了通过网格的最优路径，这个矩阵通过一个单独的函数metric(x,y)给出，这个算法既能用于硬判决译码也能用于软判决译码。 (BPSK demodulation method based on viterbi decoding algorithm, survivor_state is a matrix, the optimal path of it shows through the grid, the metric matrix through a separate function (x, y), the algorithm can not only used for decoding hard decision can also be used to the soft decision decoding. )

说明：  三种常用的自适应波束形成算法，LMS、RLS、SMI，用于产生雷达发射方向图(Three commonly used adaptive beamforming algorithms, LMS, RLS and SMI, are used to generate radar transmitting pattern)

改程序模拟了，对前推回代方法计算配电网潮流计算，迭代次数少(Modified simulation on forward and backward substitution method, calculation of distribution network power flow calculation, less iteration )

说明：  对不稳定数据进行去趋势处理，得到平滑拟合曲线。(The unstable data were de trended to obtain a smooth fitting curve.)

mathworks也提供Curve Fitting Toolbox，不过要钱，这是一个一维Curve Fitting的工具包，提供命令行和GUI接口。(MathWorks also offers Curve Fitting Toolbox, but for money, this is a one-dimensional Curve Fitting tool kit, providing the command line and GUI interface.)
