ellipse

The aim of this book is to teach you the ssentials of spectral collocation methods with the aid of forty short Matlab programs, or M-les

在matlab，传统的边缘检测直接调用edge函数，但是得到的边缘信息较稀薄，可以通过将sobel,roberts,prewitt三种算子的边缘检测叠加起来，并且对于连续的边缘部分拓宽，使得边缘更连贯清晰(In matlab, traditional edge detection edge direct call function, but thinner than the edge information can be obtained by sobel, roberts, prewitt three edge detection operator stack up, and for widening the continuous edge portion, so that the edge is more consistent clear)

里面包含emd工具包HHT工具包eemd工具包，还有eemd边际谱算法，已经试验过可以用的(Emd kit which contains HHT kit eemd kit, there eemd marginal spectrum algorithm has been tested can be used)

交互信息EXIT图的构建，有助于多迭代算法的理解(Interactive information on EXIT chart building, contribute to the understanding of the iterative algorithm)

说明：  条带法求轴力 matlab小程序 条带法求弯矩 matlab小程序(Strip method the axial force)

基于matlab人工神经网络在数据处理的运用。(Based on artificial neural networks used in data processing.)

画出二阶戴维南RC等效电路的奈奎斯特曲线和一组数据的三维散点图，剖面图(Draw the second-order thevenin RC the Nyquist curve of equivalent circuit and a set of 3 d scatter plot of data, profilet)

用matlab追迹子午光线，处理像差问题(Meridian ray tracing using matlab to deal with the problem aberration)

信道编码线性分组码hamming码的编码器译码器设计与仿真实现。(channel coding linear block code hamming yards Encoder Decoder Design and Simulation.)

dijkstra矩阵算法，可以计算出最短路，第一次上传请见谅~(dijkstra很有用的！)
