forrow结构~Matlab编写~仿真成功(farrow)

分岔图程序，非常值得参考与借鉴，很实用的一个小程序。(The bifurcation diagram program is very worthwhile reference and learn from a very practical program.)

水声通信面临的最困难的问题是多途干扰,其中自多途引起接收信号的幅度衰落,互多途引起接收信号的码间干扰,再加上海洋环境的高噪声背景、低的载波频率、极为有限的带宽以及传输条件的时间—空间—频率变化特性,使得通信过程十分困难。此外，水声通信试验的成本高，难度大，也为水声通信研究带来挑战。 本软件对水声信道的仿真研究很有帮助，可以产生声线图，冲激响应，声速图等仿真文件，结合Matlab画图工具绘制图像，对水声信道的模拟仿真很有帮助。(The most difficult problem faced by underwater acoustic communication is multi-path interference, which since multipath fading caused by the magnitude of the received signal, and mutual inter-symbol interference caused by multipath signal reception, plus the marine environment of high background noise, low carrier frequency , very limited bandwidth and transmission conditions of time- space- frequency characteristic such that the communication process is very difficult. In addition, the high cost of underwater acoustic communication experiment, difficult, and challenges for the study of underwater acoustic communication. This software is useful for simulation study of underwater acoustic channel can produce sound chart, impulse response, sound velocity diagrams simulation files, combined with Matlab drawing tools to draw the image of underwater acoustic channel simulation helpful.)

本程序是求解神经电HH方程的较为简单的例子。可以帮助大家了解神经放电的问题(This procedure is to solve HH equation ENoG more simple example. Can help everyone understand the problem of nerve discharge)

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)

说明：  从国外网站上下载的关于压缩感知分类的例程(Downloaded the foreign websites on compressed sensing classification routines)

good resource file for the iron ball detection.It introduces the good method for the researcher.

使用waterfilling 和 equal power进行power allocation(use waterfilling method & equal power to allocate power)

该程序用于惯性导航系统误差模型中，求解最优增益，然后用增益引入阻尼。(Kalman filter in INS)
