快速扩展随机生成树算法，多机电力系统仿真及其潮流计算，计算十字叉丝的在不同距离的衍射图像。( Rapid expansion of random spanning tree algorithm, Multi-machine power system simulation and flow calculation, Calculation crosshairs diffraction image at different distances.)

adomian 分解法 求解非线性常微分偏微分方程 很有效(adomian decomposition method)

In this file you can find the rayleigh fading channel. you can use matlab to open it.

这是一个实现拉格朗日插值的数学程序，也很经典。(This is a mathematical realization of Lagrange interpolation process is also very classic.)

说明：  本程序实现了采用聚类法对图像进行分割，给出了图像分割前后的直方图，程序内有详细的程序说明和例图像(This program was realized using clustering method for image segmentation is presented, and the histogram image segmentation, procedure in detail program)
