power spectrum analysis of the audio fingerprint system(power spectrum analysis of the audio finger rprint system)

说明：  这是个关于软件方程的运行代码，很简单，有需要的朋友可以下载看下，对你或许有帮助。(This is the operation code of the software equation is very simple, a friend in need can be downloaded to look, you may have to help.)

这是一个用于解决非线性最小二乘优化问题的Matlab程序，(This is a guarantee nonlinear least squares optimization problem of Matlab program.)

使用MATLAB发送邮件。当程序较大时，在结尾调用这个函数，执行完自动给你的邮箱发信息提醒你程序跑完了。(Use MATLAB to send mail. When a larger program, at the end of this function is called, d automatically send information to your e-mail to remind you ran the program.)

计算每个IMF分量及最后一个剩余分量residual与原始信号的相关性;计算各IMF的方差贡献率;绘制FFT频谱(The correlation between each IMF component and the last residual component residual and the original signal is calculated; the variance contribution rate of each IMF is calculated; and the FFT spectrum is drawn.)

PDF制作 主要看画PDF相关功能。其他的无用哦。(PDF produced primarily PDF-related features painting. Oh, the other useless.)

MUSIC algorithm for spectrum estimation

gd power system 1-22

遗传算法应用举例，在使用时可根据具体情况做修改(Application examples of genetic algorithm, when used according to the specific circumstances to make changes)

该源码是基于matlab编写Asaoka算法，用于高速铁路沉降预测(The source code is written in matlab Asaoka based algorithm for high-speed railway settlement prediction)
