提取共振峰主程序，方法很特别，非常实用，欢迎查看！(Formant )

利用PSO算法优化SVM向量机参数。测试指标为MAPE和均方根误差。(Optimization of SVM Parameters by PSO Algorithm. The test indexes are MAPE and root mean square error.)

这个代码是根据已经得到的权值矩阵，来进行分类(This code is based on the weight matrix has been to classify)

说明：  本程序展示了二维归一化互相关用于 &nbsp 模式匹配和目标跟踪。该程序提示用户选择感兴趣的（ROI）的区域和对同类目标进行跟踪的数目。归一化交叉相关图表明，当值已超过设定的阈值时目标就已经确定。(This demo illustrates the use of 2-D normalized cross-correlation for pattern matching and target tracking. The demo prompts the user to select the Region of Interest (ROI) and the number of similar targets to be tracked. The normalized cross correlation plot shows that when the value has exceeded the set threshold, the target has been identified.)

数字滤波器在数字信号处理领域中已经得到广泛应用,MATLAB 软件的频谱分析和滤波器的分析设 计功能很强,从而使数字信号处理变得十分简单。利用MATLAB 的数字滤波器设计工具箱可以快速有效地设计各种数字滤波器,设计简单方便。介绍了IIR 数字滤波器的设计原理、步骤以及在MATLAB 中的实现。(Digital filter in the field of digital signal processing has been widely used, MATLAB software for spectrum analysis and filter analysis and design features strong, so that digital signal processing have become very easy. MATLAB using the Digital Filter Design Toolbox can quickly and efficiently design of digital filters, design is simple and convenient. Introduction of the IIR digital filter design principles, steps and in the implementation of MATLAB.)
