关于近来很火的灰色预测理论的matlab的源代码，移植性好，与诸位学友共同分享，共同进步(About the grey prediction theory recently very fire matlab source code, good portability, xueyou with share, make progress together)

matlab实现图上需找最短路径的迪杰斯特拉算法，寻找任一点和其他点之间的最短距离，最终结果为最短路径度量矩阵和正序路由矩阵(matlab implementation on the map to find the shortest path Dijkstra algorithm to find the shortest distance between any point and other points, the final result is the shortest path metric matrix and positive sequence routing matrix)

数据矩阵运用非负矩阵分解算法，分解得到两个低维矩阵，并用于信号分离。(The data matrix is decomposed into two low-dimensional matrices by non-negative matrix decomposition algorithm and used for signal separation.)

A set of functions to calculate Hu s seven invariant moments. Good accuracy. Written for my Project work

本程序完成的是MATLAB平台下FIR滤波器设计的GUI界面，通过简单的输入参数，我们即可进行FIR滤波器的设计。(This procedure is done under the MATLAB platform for FIR filter design of the GUI interface, using a simple input parameters, we can carry out FIR filter design.)

通过自动阈值选择方法实现图像二值化。初始阈值T是图像均值；T把图像直方图分成R1和R2两个区域；计算R1和R2均值u1和u2，选择u1和u2均值作新的阈值；重复以上步骤直到T值基本不变。(Automatic Threshold Selection；)

ns下的dd协议代码 可以进行wsn路由协议的仿真(the code of directed diffusion)

This code is written for the map transformations, affine, conformal and polynomial. It basically uses, the parameter estimation process regarding to the quality assesment.

说明：  线性卡尔曼滤波，二维状态空间模型一般的卡尔曼滤波(kalman fitering)

this program used grow the regions
