对非平稳信号进行分段、截取，再对处理过后的短时信号做短时傅里叶变换，分析其频谱特性，并找到各个时间节点的频率特性，以便分析不同事件段内的声音特征。(The nonstationary signals are segmented, and then the interception, the short-time signal after processing the short-time Fourier transform, the analysis of the spectrum characteristics and frequency characteristics and find the different time node, in order to analyze the acoustic characteristics of different event period.)

Vc+_+调用matlab的一个实例，包括matlab源文件，VC源文件，以及word和pdf文件说明(Vc+_+ call matlab one instance, including the matlab source file, VC source files, as well as word and pdf file description)

LIBSVM 是台湾大学林智仁 (Chih-Jen Lin) 博士等开发设计的一个操作简单、易于使用、快速有效的通用 SVM 软件包，可以解决分类问题（包括 C- SVC 、n - SVC ）、回归问题（包括 e - SVR 、 n - SVR ）以及分布估计（ one-class-SVM ）等问题，提供了线性、多项式、径向基和 S 形函数四种常用的核函数供选择，可以有效地解决多类问题、交叉验证选择参数、对不平衡样本加权、多类问题的概率估计等。(LIBSVM is林智仁Taiwan University (Chih-Jen Lin) Dr. develop design a simple, easy to use, fast and effective generic SVM software package, can solve the classification problems (including the C-SVC, n- SVC), regression ( including e- SVR, n- SVR) as well as the distribution of estimates (one-class-SVM) and so on, provides a linear, polynomial, radial basis function and the S-shaped kernel function of four commonly used for selection, can effectively to solve a wide range of issues, cross-validation to choose the parameters of the imbalance in the weighted sample, multi-category probability estimation.)

多网格求解泊松方程，给出并解释了一个如何使用多网格求解的过程(I give a short explanation of how to use multigrid to solve the Poisson equation in cylindrical coordinates for a solid conducting pipe. I also explain how to use a non-uniform grid to optimize the problem. )

对想了解pc控制鼠标指针的源码的人有帮助，包括windows调用了那些函数，用了那些库文件等。(Would like to know the source pc control the mouse pointer to help people, including those functions called windows, with those library files.)

说明：  在Visual C++中调用matlab中定义的函数，可以方便利用matlab的资源(Calling Matlab defined in the function, Matlab can facilitate the use of resources)
