利用bior5.5小波对声音进行能量特征提取。小波基可以任意变换。(The sound use bior5.5 wavelet energy feature extraction. Wavelets can transform any.)

Matlab7.0，英文版的，讲的都是基础，适合初学入门者入门，很不错的资料。 (Matlab7.0, the English version, say are the basis, suitable for beginners entry, very good information.)

先定义允许状态S={(x,y)|x=0或3,y=0,1,2,3 x=y=1,2}, 允许决策D={(u,v)|u+v=1,2},求dk<-D(k=0,1,2,…,n),使 状态Sk<-S按照状态转移律S(k+1)=S(k)+(-1)^k*dk,由初始状态 S1=[3,3]经有限步到达状态S(n+1)=[0,0].此为求解多步决策问题( First define to allow the state S = ((x, y) | x = 0 or 3, y = 0,1,2,3 x = y = 1,2), to allow the decision-making D = ((u, v) | u+ v = 1,2), seek dk < -D (k = 0,1,2, ..., n), so that state Sk < -S state transition in accordance with law S (k+1) = S (k )+ (-1) ^ k* dk, from the initial state S1 = [3,3] by the finite-step to reach the status S (n+1) = [0,0]. This is a multi-step decision-making problem solving)

说明：  最小化l1范数的Matlab代码。求解模型为： min lambda*|x|_1+||A*x-y||_2。其中，|x|_1表示x的1-范数，||*||_2表示2-范数。该模型在稀疏成分分析、压缩传感器等领域有广泛的用途。( l1-Regularized Least Squares Problem Solver l1_ls solves problems of the following form: minimize ||A*x-y||^2+ lambda*sum|x_i|, where A and y are problem data and x is variable (described below). )

自学编程的必备工具之一，建立简单的模型，可以通过建立模型来提高编程能力(Teach yourself programming tool, establishing simple model, can we establish a model to improve programming ability)

现代信号处理教程清华版matlab例子源码，欢迎大家学习实用(Modern signal processing tutorial Tsinghua version matlab example source code, learn practical)

该程序是在flac下运行的，没找到flac，所以用matlab表示了，供岩土力学研究方向学习(The program is run under flac, did not find flac, so use matlab shows for rock mechanics research study)

动态LSCMA(最小二乘恒模)算法程序，空间存在3个信号，每行有注释。(Dynamic LSCMA (least square constant modulus) algorithm program, there are 3 signals in space, each line has a note.)

这个例子是书上的Morlet小波程序，运行时总是出错。包括 ??? Error using ==> CWT_Morlet at 11 At least 1 parameter required! 这个问题是怎么回事？error的用法错在哪里了？还有，这个程序还有哪些错误呢？比如函数定义之类的问题？请各位大侠帮帮我吧。( Review the release notes for other MathWorks® products required for this product (for example, MATLAB® or Simulink® ).
