这是一个matlab源码，利用小波原理进行图像压缩编码(This is a source Matlab, using wavelet theory for image coding)

The purpose of this document is to give a medium-length introduction to the essentials of MATLAB and how to use it well. I’m aiming for a document that’s somewhere between a two- page introduction for a numerical methods course and the excellent but longer Getting Started and other user guides found in the online docs. I use it in a week-long “boot camp” for graduate students at the University of Delaware in the summer after their fi rst year of study.

说明：  MATLAB6图像处理书籍，很珍贵并值得参考的(MATLAB6 image processing books, very valuable and worth considering)

Bin packing problem belongs to the class of NP-hard problems, like the others that were discussed in previous articles. The task is to pack a set of items of different size into bins of fixed size in such way that minimal number bins is used. Depending on the requirements, bin packing can be single-dimensional (1D) or multi-dimensional (2D, 3D...)

说明：  一本国外网站下载的时频分析的权威资料。我看过了，写得挺有深度的，总结得很好(A foreign Web site to download the time-frequency analysis of authoritative information. I have read, write, did well depth, summed it up well)

用matlab实现dds，并进行相关参数分析(Using matlab to achieve dds)
