计算小波变换的Mallat算法需要逐级分解和重构，而本文通过矩阵变换方法，给出不需逐级计算的小波分解和重构矩阵的构造方法，并给出9/7小波的分解和重构矩阵的基向量及波形图。-Calculation of the Mallat algorithm of wavelet transform decomposition and reconstruction needs level, and this article through the matrix transformation method of calculation without level wavelet decomposition and reconstruction of the structure matrix method of 9/7 wavelet decomposition and re- conformation of the base matrix and the wave vector.
