Automatic integration of functional differential equations: an approach, ACM TOMS, 1 (1975) 357-368.一文中的时滞微分方程求解程序。(Example 1 of K.W. Neves, Automatic integration of functional differential equations: an approach, ACM TOMS, 1 (1975) 357-368.)

熵权法求指标权重,R为输入矩阵,返回权重向量weights(Entropy weight method)

利用matlab开发平台针对算术编码原理实现了算术编码(Matlab use development platform for the realization of the principle of arithmetic coding arithmetic coding)

Binary erosion and dilation, with fast iterative calls. For any structuring element other than square or disk this function is way faster than imerode.m and imdilate.m (more than an order of magnitude). It s also handy when you don t have the Matlab Image Processing Toolbox :-)... It also allows very fast iterative calls (for instance when sweeping the structuring element while looking for a certain effect, threshold in image statistics, etc). See the help in bmorph.m and the attached .pdf file.

This code is a particle swarm optimization for localization in wireless sensor networks
