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.)
