可轻松实现短时傅里叶变换及对应逆变换，可更改程序内部窗函数，自行选择合适窗函数进行分析(Short-time Fourier transform and corresponding inverse transform can be easily realized. The internal window function of the program can be changed and the suitable window function can be selected by oneself for analysis.)

在matlab中，检测出人脸，该文件包括文章和代码(FACE DETECTION USING LOCAL SMQT FEATURES AND SPLIT UP SNOWCLASSIFIER)

otsu threshold, run on image to get value, then do binary thresholding

帮助了解matlab各种显示函数的用法，方面图像的分析(display function)

用修正协方差法对信号进行频率估计，并通过仿真图形得出该方法的优缺点。(The modified covariance method estimates the signal frequency, and graphics obtained through the simulation of the advantages and disadvantages of the method.)

根据图片手动选取像点，根据一定的组合顺序选择一定数量的像点，进行摄像机标定内外参数(According to the pictures manually select the image, based on a combination of a series of selecting a certain number of points, inner and outer parameters of camera calibration)

先进PID控制及其MATLAB仿真（教材+相关程序），本书从 MATLAB 仿真角度系统地介绍了 PID 控制的基本理论、基本方法和应用技术，是作者多年来从事控制系统教学和科研工作的结晶，同时融入了国内外同行近年来所取得的新成果。(Advanced PID control and MATLAB)

交互式多模型在很多地方都有非常大应用作用，这里面是一个完整的仿真实例，同时里面包含IMM的模块化编程，应用着可以很轻松的运动这些模块。(Has a very large role in interactive multi-model applications in many places, there is a complete simulation example, which contains the same modular programming IMM, the application can easily forward movement of these modules.)
