These are the source codes of the book, Frazier M W. "An Introduction to Wavelets Through Linear Algebra" [M]. New York: Springer, 1999. I wrote them in 2007. All the figures in the book can be reproduced by scripts. Enjoy it.

本程序演示了如何对wav进行分析并根据其数据模拟出波型图.再对其波型图进行操作.移动或者修改或者重叠.对有这方面接触的VB程序员很有帮助.-This procedure demonstrates how to wav analysis and data in accordance with its simulated waveform Fig. And then its wave-type plans to operate. Mobile or modify or overlap. For there is very helpful to contact VB programmers.

音乐，电子音乐合成。12分律 1.在钢琴演奏中G音的和弦我们常用G7和弦.不用G和弦.为什么?  2.在乐理中G7和弦5724组成音中2音省略只用574为什么?(和声学中五级七和弦省去第五音) 在12平均律中音的频率 G4=392.00Hz B4=493.89Hz D4=293.66Hz F4=349.23Hz  在纯律中音的频率 G4=396.00Hz B4=495.00Hz D4=293.33Hz F4=352.00Hz  在纯律中D音二个的频率.一个由G和弦产生297.00Hz另一个由Dm和弦产生293.33Hz  G4=396 D=396x3/2/2=297 (钢琴无这个频率)  A4=440 Dx3/2=440 D=293.33 (5度相生律.12平均律.纯律皆D=293)  当前G和弦 D4音=293.33Hz故不会合谐.当D4音=297Hz 才会合谐所以G和弦不会合谐  G7和弦才会合谐.因此有经验的作曲家在配合弦时常用G7和弦而不用G和弦.
