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)

一篇好文章，海杂波FRFT域的分形特性及目标检测(good paper)

两个matlab程序，一个实现图像的桶型畸变（Barrel Distortion），另外一个可以还原已经桶形畸变的图像(Two matlab programs,one is able to translate picture to Barrel Distortion.the other can return the translated picture.)

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.)

一种分形维数的计算方法，一种分形维数的计算方法(A fractal dimension method, a fractal dimension calculation)

说明：  用VB写的mondebroot集，鼠标选中区域可放大显示(VB wrote mondebroot set, the mouse can enlarge selected regional show)

WXH-斐波那契数列.Koch曲线 动态的Von Koch分形曲线,中点法生成Sierpinski地毯 分形蝴蝶 (WXH-Fibonacci sequence. Koch curve dynamic Von Koch fractal curve, the mid-point method to generate fractal Sierpinski carpet Butterfly)

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.)

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 )

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.)
