通过时空变换的方法对超声导波模态提取，可以用于声发射和超声导波提取模态用(Through time and space to transform Ultrasonic Guided Wave Mode extraction, can be used for acoustic emission and ultrasound guided modal wavelet extraction using)

Here the syms toolbox is used and if you try to print any other values than lambda then MATLAB will print the value in fractions and that is unavoidable. So if you need to know the value in decimal, then use the command vpa() on command window

这是一个用AnCAD公司的matfor图形包写的一个小程序，实现了类似matlab封面三维图形功能，用该图形包代码量少，个人认为比matlab更能满足用VC开发的朋友。(This is a company with AnCAD graphics package matfor write a small program to achieve a similar three-dimensional graphics functions matlab cover, using the graphics package code less, think more than matlab personal use VC development to better meet friends.)
