滤波器设计是信号处理的核心问题之一,Matlab软件在多个研究领域都有着广泛的应用。 本文介绍了基于Matlab环境下,用窗函数设计法实现FIR数字滤波器的设计,并阐述了与以前人 们常用的设计方法的区别,给出了设计实例。仿真结果表明,设计结果的各项性能指标均达到指定 要求,且设计过程简便易行。 (The design of filters is a core problem in signal processing. MATLAB software iswidely used inmany research fields. This article introduces themethod ofusingwindow function to design FIR digital filters based onMATLAB and its differences from the tradi- tional designmethods. And itgives a design example. The simulation shows that the design results canmeet the requirements verywell and the design procedure is very simple and practica.l )

"Space-Time Codes and MIMO Systems"是Mohinder Jankiraman 所著的经典之作，这里给出全书的matlabe源码。 电子版书籍另外给出。 ("Space-Time Codes and MIMO Systems" is Mohi nder Jankiraman author of classic works, here is the book matlabe source. Electronic version of books is another.)

Particle filter implementation for matlab

Matlab编写的REOF程序，比EOF更能刻画局部特征。(The Matlab' s written REOF the program more than EOF portray local features.)

材料科学中退火算法的最新模拟方法，大家看看拉。(Materials Science in the latest simulation annealing algorithm, we look at Latin America.)

该算法的功能是利用避圈法来求有权图的最小生成树 在函数的编写过程中用到了自己编写的 wode_setdiff(A,b) 函数，具体详参该函数 该算法的实用性相当强，可以实用于任何的赋权有向图最小生成树的求解！！！经过多次不同的运行， 程序的结果都正确无误！(the function is...)

说明：  直接将matlab中的数据，图像，表格窗口存入到ppt里。(Matlab data directly into the ppt there.)

用MATLAB实现带状矩阵A的LU分解，参数为A的主对角线元素组成的列向量(A MATLAB implementation by the LU decomposition of banded matrix, the parameters for the A' s main diagonal elements of the column vector)

水印的嵌入，在图象中嵌入水印，以提高安全性与可靠性(Embedded watermark, the watermark embedded in the images to enhance the security and reliability)

小波阈值去噪算法的几个例子。希望对广大的初学者有点帮助。(Wavelet threshold denoising algorithm a few examples. I hope the majority of the beginners a little help.)
