metrix_vif

此程序用于实现结构的有限元计算：将patran中的模型的bdf文件中的单元信息和节点信息保存成txt文档，在matlab中调用，就可实现刚度矩阵、质量矩阵的组装，进而有限元计算(This procedure is used to achieve the structure of the finite element method: bdf file of the model in patran unit information and node information is saved into a txt file called in matlab, you can achieve the stiffness matrix, mass matrix assembly, and then the finite elementcalculate)

解优化问题时常用的惩罚函数法，分为内点法和外点法两种，求解约束优化问题最优值。(Penalty function method, including interior point method and exterior point method, to solve the optimal value of constrained optimization problems.)
