OFDM的理解学习，研究并在MATLAB上编译，有助于理解OFDM传输机制。(a program for studying OFDM.)

Shunt Generator equation

说明：  采用一种离散微分跟踪器的PID控制。被控对象是三阶传递函数，参考输入rin=20，干扰信号是0.5rands（1）。(PID Controller with Partial differential)

这是一本关于MATLAB的电子书，格式是PDF，里面介绍很详细，是新手学习的好帮手。(This is a book about MATLAB format is PDF, which introduced a very detailed novice learning a good helper.)

matlab例子，用来计算bezier曲线(matlab example, used to calculate the Bezier curve)

对FFT加汉拧窗操作，减少FFT产生的漏频效应和阑珊效应。(Add Chinese twist on the FFT window of operation, reducing leakage resulting FFT frequency effect and discouraged effect.)

this is good source. try to explore it. and also youll find usefull when need to develop ica cases.

Clustering 和 SVM 结合的预测模型算法。聚类采用k-means方法，SVM采用lib-svm工具箱。(kMeans and SVM(support vector machine) prediction model is provided.)

介绍了数字通信中的QPSK调制解调的原理，通过用Matlab编写脚本程序对QPSK通信系统的发射和接收过程的具体实现进行模拟仿真，绘出信号在理想信道和加噪信道中模拟传输时的时域图，并对各模块进行了频谱分析，所得到的结果与 理论基本相符，对于理解QPSK系统的性能并在系统的实际应用上作进一步的设计，提供了有效的参考依据。 (The introduction was done with the principle of the QPSK modulation and demodulation in digital communications，a script was written by using Matlab program to CalTy out a simulation of the QPSK communication system．which contains the concrete realization of transmit and receive process．The time-domain diagram is drew separately when the signal transmits in the ideal channel and in the channel with noise，spectral analysis of each module is also done，the results obtained with theoretical results in the main，which provides an effective frame of reference for understanding the performance of QPSK systems，and the practical application in the system to make further designed．)

Simple exception class used to communicate that the command-line tool should print the usage message.
