Matlab simulation program of a coating machine can be used for the simulation and validation of the control method

说明：  描述颗粒形貌边界的分形维数程序。其中4.bmp是需要被分析的图片名称。使用者自行修改。(Description of particle morphology of the border fractal dimension of the procedure. 4.bmp which need to be analyzed is the name of the picture. Users to make its own decisions.)

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.)

说明：  程序可以在matlab环境下，用矩形面元为绘制三维立体分形曲面(procedures in Matlab environment, with rectangular surface yuan for three-dimensional mapping of fractal surfaces)

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)
