非常著名的曲线拟合程序，很长，要看懂需要花不少的时间。内含例题-A very famous curve fitting program,very long,it s needs much time to understand it.Include samples

模式识别中的最大最小距离算法，这程序处理二维数据，我发现网上的程序都是设置一个很大的数组，但本程序是无论多少数据样本都可以处理的。结果存放在两个数组中，z数组存放中心数据，r数组的cente是样本所属的S-Maximum and minimum distance algorithm in pattern recognition, this program deal with two-dimensional data, I found the online program are set to a

This MATLAB M-file implements the finite-difference time-domain solution of Maxwell s curl equations over a two-dimensional Cartesian space lattice comprised of uniform square grid cells. To illustrate the algorithm, a 6-cm-diameter metal cylindric
