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.)

please give matlab coding

MUSIC算法是基于天线阵列协方差矩阵的特征分解类DOA算法，这里给出的是经典MUSIC源程序。(MUSIC algorithm is based on the characteristics of the antenna array covariance matrix decomposition class DOA algorithm presented here is the classic MUSIC source.)

说明：  该程序计算元胞自动机凝聚扩散的实例，附加判断二维数组的元素及其个数(The program calculated the proliferation of cellular automata examples of cohesion, the additional two-dimensional array to determine the number of elements and their)

移动通信中的新技术simo技术信道容量仿真(The new technology of mobile communication simo technology channel capacity simulation )

说明：  曲线拟合 matlab 毕业设计常用 (use matlab curve fitting )

解决最小费用最大流问题，一般有两条途径。一条途径是先用最大流算法算出最大流，然后根据边费用，检查是否有可能在流量平衡的前提下通过调整边流量，使总费用得以减少？只要有这个可能，就进行这样的调整。调整后，得到一个新的最大流。(Minimum cost maximum flow problem to solve, there are generally two ways. One way is to use a maximum flow algorithm to calculate the maximum flow, then the cost side, check whether it is possible under the premise of the flow balance by adjusting the edge flow, so that the total cost can be reduced? As long as this possible, for such adjustments. Adjusted to obtain a new maximum flow.)

matlab的降维工具箱 从官网上下载的(Dimensionality reduction downloaded the official website matlab toolbox)

Newton s method for solving system of nonlinear equations.

matlab数字水印算法及实现和源代码 功能很强大 (Matlab digital watermarking algorithm is proposed and realized and the source code)
