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.)

从变量可见性角度分析，Matlab程序运行过程中（以下不特别说明都是指在Matlab程序中），不同形式的变量可见范围源于于面向对象编程的概念.(variables can be seen from the point of view of analysis, Matlab procedures in the process (not refer specifically explain procedures in Matlab), different forms of variable can be seen in the area stems from the object-oriented programming concepts.)
