DFT

关于DSP方面的低通滤波器的设计的matlab程序。(On the DSP side of the low-pass filter design matlab program.)

matlab的getframe有时候并不能截取画出来的3D图像(而是截取出一个空坐标系).该程序用matlab调用windows的截图功能, 真正实现了原封不动的截图.(但是耗时会长一点). 使用时, 先把文件夹添加到matlab的路径下即可.文件夹中有两个功能略有不同的函数printScreen是截取整个屏幕, printFigure是截取整个屏幕后挖出当前的Figure窗口中的内容.(matlab does not intercept the getframe sometimes drawn 3D images (but the interception of an empty frame) The procedures used to call matlab windows screenshot function, truly untouched screenshot. (but a little time consuming president ) When using, first add a folder to the matlab' s path. folder has two functions is slightly different function printScreen intercept the entire screen, printFigure dug up the entire screen after interception current Figure window content.)

基于S函数编写了自抗扰控制器中的跟踪微分器（TD）,扩张状态观测器（ESO）,非线性反馈（NLSEF），并在Simulink环境下搭建ADRC，完成对方波的跟踪，简单好用(S function based on written ADRC in tracking differentiator (TD), extended state observer (ESO), non-linear feedback (NLSEF), and built ADRC in the Simulink environment, complete track the other waves, simple and easy use)

一些VC++的数字信号处理程序，其中包括dft，fft，卷积的运算(conv and dft)

按照文献《complex networks》中192-193页方法生成的scale free network，有详细注释。此方法有助于理解scale free network的生成原理，并画出了P（k）图，可以自己验证r值是否正确。(According to literature " complex networks" in the 192-193 page method to generate the scale free network, with detailed notes. This approach helps to understand the generation of scale free network theory, and plotted the P (k) diagram, you can verify their r value is correct.)
