matlab软件编程指南，主要是一些常用matlab函数的说明和分析(Matlab probability statistics programming guide)

简单的matlab算法，很经典，用于波束形成，主要是MIMO雷达 (Simple matlab algorithm, very classic, for beamforming, MIMO radar)

matlab开发的滤波器有程序 使用简单方便 值需要改几个参数就可以实现对任何信号的滤波 程序中还就如了相关注解 有利于读者理解！(matlab filter developed procedure is simple and convenient to use the value of the need to change a few parameters can be achieved for any signal of the filtering process also, such as the relevant comments in favor of reading!)

说明：  这是灰色GM(1,1)预测的源代码，只要你输入数据，就可以预测以后的数据，必要时可以修改程序(This is a gray GM (1,1) forecast of the source code, as long as you input data, the data can predict the future, if necessary, modify the program)

一个关于MUSIC算法的源程序，有一点问题，哪位高手帮忙看看为什么不能运行，谢谢了！(one on the source MUSIC, 1:00. Which expert help to find out why not running, thank you!)

双线性变换法设计Butterworth滤波器。分别画出滤波前和滤波后的时域图和频谱图。(Bilinear transform design Butterworth filter. Draw the pre-filter and the filtered time-domain and frequency spectrum.)

一个小巧有限元计算软件fem的licence和一个例子(A compact fem finite element software and an example of licence)

说明：  粒子群算法（PSO）应用于神经网络优化，采样matlab编程(Particle swarm optimization (PSO) applied to neural network optimization, sampling matlab programming)

matlab4.2 数值计算与编程 版本稍微有点老，还是有参考价值的(Numerical Methods and Programming matlab4.2 slightly older version, or a reference value)
