说明：  生成含噪声的信号，并进行小波分解以及分析(Generate noisy signal, and wavelet decomposition and analysis)

Matlab function to generate a random vector with entire values without repetition.

这是数字信号处理的几个典型例程，都是有关于最基本概念方面的，对初学者有帮助(Digital Signal Processing This is a typical course of a few are on the most basic concepts, and helpful for beginners)

说明：  嵌入式系统的建模及matlab仿真，同时给出相应的C++实现代码(failed to translate)

利用目前风力机叶片设计普遍采用的优化设计方法Wilson设计A-法，通过MATLAB编程，开发了小型叶片气动设计的应用程序，并利用该程序设计了一台3kW小型水平轴风力机叶片。采{用MATLAB和ANSYS共同建立了风力机叶片三维有限元参数模型，MATLAB编制的建模程序提高了{初期设计效率，缩短了ANSYS分析前处理时间。在此基础上进行了叶片固有振动特性计算，分析了叶《片的振动特性及其与结构参数之间的关系，分析方法和结果对风电叶片的结构设计和动力分析有一定；的参考价值。(Advantage of the current design of wind turbine blades commonly used in optimal design method Wilson designed the A-Law, MATLAB programming, developed a small blade aerodynamic design application and use of the program designed a 3kW small horizontal axis wind turbine blades. Mining {using MATLAB and ANSYS common parameter model of wind turbine blades dimensional finite element modeling program MATLAB prepared the {initial design efficiency, shortening the ANSYS analysis of the pre-treatment time. On this basis, the natural vibration characteristics of leaves, the relationship between leaf on vibration characteristics and structural parameters, analytical methods and the results of analysis has some structural design of wind turbine blades and power reference value.)

function [x, hist] = secant(x, f, tola, tolr) SECANT This a secant code with no line search. This code terminates on small relative-absolute errors function [X, HIST] = SECANT(X, F, TOLA, TOLR) Inputs: X = initial iterate F = function TOLA = absolute error tolerance TOLR = relative error tolerance Output: X = approximate result

在语音识别系统中，端点检测的目的是要区分语音段和非语音段 ,它在自动语音识别中起着关键作用(In speech recognition systems, the purpose of endpoint detection is to distinguish between voice and non-voice segment, which in automatic speech recognition plays a key role)

使用simulink实现脉冲编码的仿真模块(Using simulink pulse code Simulation Module)
