天在维普下载了一篇SPIHT算法改进的论文，（耿兴云，《基于改进SPIHT的静态图像编码》，电脑知识与技术：学术交流-2007年5期），我根据该文提出的改进算法，用Matlab来实现，却发现改进算法的程序运行速度比原算法还要慢，希望有兴趣的朋友进来看看，评论一下原因。(Days in the VIP downloaded a SPIHT algorithm to improve the paper, (Gengxing Yun, " based on improved SPIHT still image coding," Computer Knowledge and Technology: 5-year academic exchange-2 007), in accordance with this paper the improved algorithm Matlab to achieve, but found that the improved algorithm runs faster than the original algorithm is also slow, hope to have interested friends come to see, comment on why.)

进行了基本的扩频中的 低检测、电器性检查、分集、瑞丽衰落等等的仿真 运行过(the basic spreading the low detection, electrical inspection, diversity, Ruili decline, and so on the simulation run-off )

In this document has been introduced comprehensively how to solve different partial differential equations .Everbody can solve Heat Conduction Equation, Helmholtz Equation, Laplace Equation and Wave Equation for different initial and boundary conditions. This document is elemantary of to understand how to solve partial differential equations with the aid of a porgramming language.
