用迭代函数ifs画分形几何，非常有用，可以仿真画自然界的几何事物(iteration function ,fractal geometry ,ifs)

根据三角形细分法原理，设计的分形山绘制程序，添加了图像美化的功能(According to the principles of the triangle subdivision, mountain fractal design drawing program, add a picture landscaping features)

计算分块灰度图像的分形盒维数技术的源代码(Calculation sub-block gray-scale image of the box dimension of fractal technology in source code)

大自然的分形几何学（最新修订本），该书是pdg格式图书，对分形几何学习有重要作用(this book is a classical book for study fractal)

用matlab语言来简洁的实现在静态负载下符合最小化原理的拓扑优化。总共只需要输入99行代码，包括优化程序和有限元分析子程序。这99行代码中，其中36行为主程序，12行为基于最优控制器的优化程序，16行为敏度过滤分析，其余35行代码作为有限元分析。(MATLAB language is used to concisely implement topology optimization based on minimization principle under static load. A total of 99 lines of code are required, including the optimizer and the finite element analysis subroutine. In these 99 lines of code, 36 behavior main programs, 12 behavior based on optimal controller, 16 behavior sensitivity filtering analysis, and the rest 35 lines as finite element analysis.)

用matlab实现的计算记盒分形维数的程序(Calculated using matlab record box fractal dimension of the process)

这属于絮凝分形成长模拟中的DLA模型，让单个粒子去碰撞总粒子，然后判断是否聚集黏附(Flocculation fractal growth simulation)

计算1D,2D,3D的分形盒维数，国外网站下载，感觉不错(Calculation of 1D, 2D, 3D box fractal dimension, foreign website, I feel good)

N 整形变量，输入参数，矩阵A的阶数 A[] 实型数组，输入、输出参数，输入是按列存放方阵A，计算结束时输出A的逆矩阵 B[] 实型数组，输入、输出参数，输入时按列存放实方阵B，计算结束时输出（A逆*B—）( Gauss Jordan elimination )

我在分形课程上用的仿真程序，有mandbort和LOGISTIC、Rossler、Lorenz等几个集合图的小程序。(Fractal course I use the simulation program, has mandbort and LOGISTIC, Rossler, Lorenz several collections map applet.)
