实现傅里叶算法中的各项特性，如线性特性、频移特性、对称性、循环卷积等-Characteristics of the Fourier algorithm, such as the linear characteristics, frequency shift characteristics, symmetry, circular convolution

一维小波变换，基于Mallat算法编写，用Daubechies正交小波基作为卷积核对输入信号作卷积，对结果进行重排可得一维小波变换后的尺度系数和小波系数。-one dimensional wavelet transform based on Mallat algorithm is written, with Daubechies orthogonal wavelet base as a convolution convolution check input signal, the results
