SPIHT-algorithm
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.)

read-signal-sub-vi
可以直接读取txt格式的信号文件,一般是指振动波形数据。只需要输入目录和频率即可,出来就是波形图,该vi还对信号做了去直流的处理。(the vi can read the signal file which is writed in text formation。)
