Ecg analysis using wavelet transform

对利用录音设备对手机、电话等按键式密码输入终端进录音盗取银行卡密码的不法行为进行技术分析，利用MATLAB软件编程对按键式密码输入终端的按键音进行音频分析，基于短时能量和过零率对所采集的音频文件进行端点检测，提取出单个拨号音，然后对处理后的音频进行频谱分析、对比，从而识别按键式密码输入终端的按键音。(On the use of recording equipment on the phone, telephone touchtone input terminal password into the recording steal bank card passwords wrongful conduct technical analysis using MATLAB software programming for touch-tone touchtone password input terminal for audio analysis, based on short-term energy and zero-crossing rate of the acquired endpoint detection audio files, extract single dial tone, and then processed audio spectrum analysis, comparison, to identify key tone touchtone password input terminal.)

This code has been used and seems to be free of error. However, it carries no explicit or implicit guarantee.

MATLAB提供了各种曲线拟合方法，例如：Exponential, Fourier, Gaussing, Interpolant, Polynomial, Power, Rational, Smoothing Spline, Sum of Functions, Weibull等，当然，也可以使用 Custom Equations. cftool不仅可以绘制拟合后的曲线、给出拟合参数，还能给出拟合好坏的评价参数(Goodness of fit)如SSE, R-square, RMSE等数据，非常好用。但是如果我们已经确定了拟合的方法，只需要对数据进行计算，那么这种GUI的操作方式就不太适合了，比如在m文件中就不方便直接调用cftool。 (matlab has given a lot of method for curve combine ,we will give a new method and provide a matlab code.)
