Matlab基础与应用教程 书本习题答案(Matlab Fundamentals and Applications tutorial books Exercise answers)

一个 Matlab GUI 程序，可以进行一些基本的 Smith chart 运算 (A GUIDE GUI for basic smith chart operations. This set of files gives a easy to use smith chart. Basic smith chart operations can be carried out in a graphical user interface. This interface is created with GUIDE. This interface can work only with MATLAB relese 6.5 (Rel 13) or later)

说明：  剪切波代码实现 有Matlab和python两个版本 都是可以运行和跑通的(The implementation of shear wave code has two versions: MATLAB and python, which can run and run.)

这个matlab程序实现了Edge Linking and Line Segment Fitting，解压后直接运行demo.m就可以了 ( edgelink.m edge linking function that forms lists of connected edge points from a binary edge image. (Needs findendsjunctions and cleanedgelist below). drawedgelist.m plots out a set of edge lists generated by edgelink or lineseg. edgelist2image.m transfers edgelist data back into a 2D image array. lineseg.m forms straight line segments fitted with a specified tolerance to the lists of connected edge points. maxlinedev.m is also used by lineseg.m to calculate deviations of the edge lists from the fitted segments. findendsjunctions.m finds line junctions and endings in a line/edge image. cleanedgelist.m cleans up a set of edge lists generated by edgelink or lineseg so that isolated edges and spurs that are shorter than a minimum length are removed.)
