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.)

This problem is main to solve a PDE. And we have validate hte program with the analysis results.

在小波分析及其变换中，Hurst指数的Matlab实现(Wavelet analysis and transformation, Hurst exponent of Matlab achieve)

1.理解显式差分格式的依赖区域。写出所给微分方程的依赖区域。 2.会求显式差分格式的截断误差。 3.能写出显式差分格式的CFL条件，显式差分格式的稳定性条件，写出显式差分格式的收敛性条件。 (Understanding the explicit difference scheme dependent region. Write to differential equations dependent region. 2 will seek explicit difference scheme truncation error. Explicit Difference Scheme CFL conditions, the stability condition of the explicit difference scheme able to write, write explicit difference scheme convergence conditions.)
