说明：  我编写的利用trous（多孔算法）实现小波变换，利用‘db4’小波函数分解两层，其中卷积运算采用频域的fft算法，给出了仿真信号的处理结果。(prepared by the use of trous (porous algorithm) to achieve wavelet transform, use 'db4' wavelet decomposition layers, which used convolution operators fft the frequency domain algorithm, given the signal processing simulation results.)

采用某种算法对样本进行分类，当有新的样本时把它们归到哪一类中，可以采取一些工具箱(Using an algorithm to classify the samples, when new samples to a class where they go, you can take Toolbox)

This is the program to find the local minima of the histogram and then to find the smooth function of the graph
