用巴特沃斯逼近以及双线性实现数字滤波器的设计~~！！(iir)

说明：  对一列数据波形进行画图，频谱、功率谱分析。参数根据需要改动一下即可(Waveform data of a drawing, spectrum, power spectrum analysis. Click to change parameters as needed)

这是＜小波分析与信号处理——理论、应用及软件实现＞的电子版书籍(<wavelet analysis and signal processing-- Theory, Application and Software> electronic version of books)

用快速傅里叶变换实现图像融合，将一个人脸上的妆融合到另一个人脸上(With fast Fu Liye transform image fusion, a person will face makeup into another face.)

小波分析由于具有同时分析信号时域和频域的特性，所以使用小波分析技术对检测的信号进行变换，然后对具有故障特性的信号进行重构，最后通过希尔伯特变换进行解调和细化频谱分析，从而轴承中的故障信息成分就可以检测出来，以判断轴承发成故障的部位。(Wavelet analysis has the characteristics of both time and frequency domain, so the wavelet analysis technique is used to transform the signal, then the signal is reconstructed. Finally, the fault information components of the bearing can be detected by Hilbert transform.)

说明：  正态总体参数的检验,调用ztest和ttest函数(Inspection normal population parameters)
