On Sunday, April 27, 2003, Fresno will celebrate Earth Day in downtown Fresno at Courthouse Park. The event will begin at noon. This year we will include music, speakers, and vendors, plus activities for children. Fresno Earth Day is recognized as the only Earth Day festival that happens in Fresno, and the largest in the Central Valley. The Fresno Earth Day Committee is a small group of environmental activists hoping to broaden the appeal of a better planet and environment. We are a non-profit organization whose fiscal fiduciary is the Fresno Center for Nonviolence.(On Sunday, April 27, 2003, Fresno will celebrate Earth Day in downtown Fresno at Courthouse Park.

一个很不错的误码率仿真介绍，看后会明白Matlab的误码率仿真原理！(A very good simulation of the BER introduced to understand after watching the bit error rate Matlab simulation principle!)

说明：  matlab实验指导书，对学习matlab有很大的帮助，欢迎下载。(matlab experimental guide books, to learn matlab great help, please download.)

续上一个程序的线性控制律的滑模变结构控制源代码，在二级摆上进行实验，调试运行正确。(continued on a linear process control law SMVSC control of the source code, in the top two experiments Debugging operating correctly.)

验模态分解（Empirical Mode Decomposition,简称EMD）是一种自适应信号分解方法,主要应用于非线性非平稳的信号。整体平均经验模态分解（Ensemble Empirical Mode Decomposition,简称EEMD）解决了EMD中出现的模态混合问题。(Ensemble Empirical Mode Decomposition)

说明：  帮助matlab载入.sif文件，从而读取并处理文件内容(Help matlab load. SIF file to read and process file content)

说明：  网络函数逼近实例1.首先定义正弦函数，采样率为20Hz，频率为1Hz 2.生成BP网络。用newff函数生成前向型BP网络，设定隐层中神经元数目为10 3.对生成的网络进行仿真并做图显示。 4.训练。对网络进行训练，设定训练误差目标为 1e-5，最大迭代次数为300 5.再次对生成的网络进行仿真并做图显示。(Network function approximation example)

Matlab 中常用的图像图像处理源程序。(Image processing method and program)

说明：  基于背靠背双PWM的永磁直驱风电系统模型，亲测可用。(Permanent magnet direct drive wind power system)

图像的中值滤波，能够从键盘输入窗口大小，自适应滤波(Image median filtering can be entered from the keyboard window size, adaptive filtering)
