Diffusion-limited  Aggregation（DLA）扩散限制凝聚，是由Witten和Sander于1981年共同提出来的。其基本思想是：首先置一初始粒子作为种子，在远离种子的任意位置随机产生一个粒子使其做无规行走，直至与种子接触，成为集团的一部分。然后再随机产生一个粒子，重复上述过程，这样就可以得到足够大的DLA团簇。(Diffusion-limited Aggregation (DLA) Diffusion Limitation Cohesion was presented by Witten and Sander in 1981. The basic idea is to first set an initial particle as a seed, at any position away the seeds randomly generated a particle to make it random walk until the contact with the seeds, as part of the group. And then randomly generate a particle, repeat the process, so you can get enough large DLA clusters.)

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.)

计算图像分维的几个程序，都已测试过，效果不错！(Calculation of fractal dimension images of a few procedures have been tested, good results!)

多边形合并操作算法。采用C++编写。可以执行。(Polygon merging operation algorithm. )

求故障树的 1）对偶树； 2）最小割级和最小路集； 3）假定底事件的故障概率已知，求顶事件发生的概率； 4）求底事件的结构重要度、概率重要度和关键重要度。(Seeking Fault Tree 1) dual tree 2) minimum cut level and minimal path sets 3) It is assumed that the end of the event of the failure probability known, find the probability of occurrence of the top event 4) Evaluate the end of the event structure importance, important degree of probability and critical degree.)

分形维数计算的毯子算法matlab代码，有一定借鉴意义(Calculation of the fractal dimension of the blanket algorithm matlab code, there is a certain reference)

分形树~~可以设置分形树的各类参数,而且较为简单(fractal tree ~ ~ fractal can set various parameters of the tree, but is much simpler)

此程序为matlab分形程序，用于计算具有分形特性的时间序列的rs分形维数，仅供参考如有错误请指正谢谢(compulate the dimenson of the time serial)

对图像进行几何变换，如旋转，缩放，镜像，裁剪等。(Image geometric transformations such as rotation, scaling, mirroring, cropping and so on . )

二维图形几何变换的实现，MFC，平移、比例、对称、旋转等(The realization of two-dimensional graphics geometric transformation, MFC, translation, proportion, symmetry, rotation, etc.)
