中文说明：mallatm2d.m:二维mallat快速分解与合成算法的演示函数，要调用mallatm.m与mallatr.m 在matlab命令行键入; 通过 matlab 实现二维离散小波变换的 Mallat 快速算法和对二维图像进行多级分解与重建，深入理解多分辨率分析与离散小波变换的联系。通过观察信号的分解系数中零所占的百分比，对小波压缩技术建立直观上的理解。
English Description：
Mallatm2d.m: rapid decomposition and composition of two-dimensional Mallat algorithm demo function to call mallatm.m and mallatr.m At the MATLAB command line, type; By MATLAB implementation of two dimensional Discrete Wavelet transformed Mallat algorithm and the multistage decomposition and reconstruction of two-dimensional images, in-depth understanding of Discrete Wavelet transform and multi-resolution analysis link. By observing the signal decomposition coefficient percentage of zero, build on intuitive understanding of wavelet compression technology.
