用矩形窗设计线性相位FIR低通滤波器,给了源代码，已经调试过了。其中要用到一个函数myfreqz要自己编，在这也附上其代码。希望对大家有用。(Rectangular window with the design of linear phase FIR low-pass filter, to the source code, have been debug. To use a function which myfreqz to own, in that its code is also attached. Hope useful for everyone.)

说明：   此程序用提升法实现第二代小波变换 我用的是非整数阶小波变换 采用时域实现,步骤先列后行 正变换：分裂，预测，更新； 反变换：更新，预测，合并 只做一层（可以多层，而且每层的预测和更新方程不同）(procedure used to upgrade Method second generation wavelet transform I use a non-integer-order wavelet transform domain when used, the first step out go backward transformation : split and forecast updates; Anti-Transform : Update, forecasting, consolidations only one (which can be multi-storey, but each floor and update the forecast equation different))

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.)
