Simulink建模与仿真。包含一本关于Simulink建模仿真的书，以及一个很好的课件。(Simulink modeling and simulation. Contains a book on the Simulink modeling and simulation, as well as a good courseware.)

说明：  在matlab环境下生成一个正方形中心嵌套一个圆，并利用curvelet变换显示出其各个子层的系数图，良好的体现了curvelet变换的各向异性的性质。(In the matlab environment to generate a nested square center of a circle, and the use of curvelet transform shows that its coefficient of sublayer maps, a good reflection of the curvelet transform the nature of the anisotropy.)

周期图法谱估计需要对信号序列“截断”或加窗处理，其结果是使估计功率谱密度为信号序列真实谱和窗谱的卷积，导致误差的产生。本程序分别设计了周期图法,最大熵功率谱估计和Welch法以及它们的对比,最大熵功率谱估计目的是最大限度地保留截断后丢失的“窗口”以外信号的信息，使估计谱的熵最大。(Periodogram spectrum estimation signal sequence needs to " cut off" or add the window handle, the result is an estimated power spectral density of the signal sequence of the real spectrum and spectral convolution window, resulting in the generation of errors. The procedures were designed periodogram, maximum entropy power spectrum estimation and the Welch method and their comparison, the maximum entropy power spectrum estimation purpose is to maximize the retention of truncated after the loss of the " window" than the information signal, the entropy of the estimated spectrum maximum.)

实现单稳触发功能，扩展输入信号为指定时常(a implement of mono，expand the input signal to a given time)

it produces a simple circle in matlab and can be used anywhere.

This program generate pitch estimation fro signal.

分类与回归。Matlab的工具箱是围绕一个快速LS-SVM训练和模拟算法。该相应的功能调用可以用于分类以及为函数估计。该功能plotlssvm显示模型的模拟结果，在训练的区域点。(The Matlab toolbox is built around a fast LS-SVM training and simulation algorithm. The corresponding function calls can be used for classification as well as for function estimation. The function plotlssvm displays the simulation results of the model in the region of the training points.)

本程序包内用matlab编写数值计算方法中的插值的源代码，包括Newton插值法，拉格朗日插值法，在mainInt.m文件中测试，并与拟合函数进行比较。供学习数值计算的程序员参考。(This program package using matlab numerical method of interpolation of the source code, including the Newton interpolation, Lagrange interpolation method, tested in mainInt.m file, and compare with the fitting function. For learning numerical Programmer s Reference.)
