拓扑优化（topology optimization）是一种根据给定的负载情况、约束条件和性能指标，在给定的区域内对材料分布进行优化的数学方法，是结构优化的一种。该程序基于matlab，提供求解约束优化问题的方法(Topology optimization is a mathematical method to optimize material distribution in a given area according to given load conditions, constraints and performance indicators. It is also a structural optimization method. The program is based on MATLAB and provides a method for solving constrained optimization problems.)
