小波分析，很方便使用，稍作修改即可，可计算小波方差，小波实部、小波虚部-Wavelet analysis, it is easy to use, with some slight modifications

对数据，信号等进行傅里叶变换，计算小波系数，绘制小波方差图等(Fourier transform to data, signals and so on Calculate the wavelet coefficients draw the wavelet variance diagram and so on)

应用小波分析来绘制小波方差图或者小波等值线图(The application of wavelet analysis to draw the wavelet variance diagram or wavelet contour map)
