matlab 学习技巧，现在把我用的，也就是对我帮助很大的留个文件传上去，希望对大家有用，第一入门与提高(matlab learning skills, and now I use, which is a great help to me to leave a document passed up, we want to be useful, the first entry and improve)

USGS ——(United States Geological Survey)美国地质勘探局。(USGS ——(United States Geological Survey))

用EWMA（garch（1，1））模型进行计算，rolling window的形式(use the method of rolling window size equals to 250, adopt EWMA model which also calls Garch(1,1) to calculate the Value at Risk)

说明：  binary genetic algorithm

说明：  本文档中的源代码是利用谱减法对语音信号进行增强，再matlab中运行可达到预期的效果。(The source code in this document is to use spectral subtraction to enhance the speech signal, and then run matlab can achieve the desired results.)

The study documents the famous 3D engine for 3D developers learn to use.

说明：  RBF逼近未知函数的滑模控制，用matlab语言编(Sliding mode control of RBF approximating unknown function)

电极系测井曲线 用matlab编写的用于学测井同学用(Electrode system logs using matlab for students with learning logs)

说明：  首先，对复杂振动信号进行EMD分解，得到各个频率分量，接着，对各分量进行Hilbert变换，得到瞬时频率(END resolve,hilbert chang,evry imf,instantaneous frequency)
