this is a mass-spring system that show the animation of mass on vertical spring by changing the initial values

输入一个任意长的数字序列，使用幅度调制法调制，然后使用包络检波法解调(Enter an arbitrarily long sequence of numbers, use the modulation amplitude modulation method, and then use the envelope detection method demodulation)

DCT变换图像处理，给出了源码和实现过程，是一个毕业设计(DCT transform)

支持向量机SVMmatlab程序源代码，能够实现对数据的预测和分析(Support the vector machine SVMmatlab source code, to achieve the prediction and analysis of the data)

自己编的程序，实现快速傅里叶变化，结果和matlab自带的fft2一样。(Own series of programs, fast Fourier transform, results and matlab native fft2 the same.)

this is a book on practical feedback control and not on system theory generally.feedback is used in control systems for two reasons,it use matlab.

通过重心法确定光斑图像的中心。根据个像素的灰度值和所在的位置乘积和总面值作比，进而求得重心。(Through the center of gravity method to determine the center of the image spot. According to the gray-scale pixel value and the location of the product and the total for more than face value, and then get the focus.)

The proposed filter is able to suppress high-density of salt-and-pepper noise, at the same time preserving fine image details, edges and textures well.
