说明：  机械优化设计作业（鲍威尔） 说明:学完优化设计，老师说要做作业，全班分为5个小组，分别用最速下降法，牛顿法，鲍威尔法，共轭.DHF 法完成： f(x)=x1^2+x2^2-x1*x2-10*x1-4*x2+60.小弟采用的是用计算方法选出d的表达式后迭代得到。分别用最速下降法，牛顿法，鲍威尔法完成了作业。 鲍威尔法最全。 功能有：输入起始点（x0，x1）和精度E 求出最优解。运算过程保存在程序目录的 txt文件中。txt自动添加标题。添加程序运行时间。等等等~ 大家可以借鉴一下
(Optimal Design of mechanical operations (Powell) Description: Learning End optimum design, the teacher said to do their homework and the whole class is divided into five groups with the most steepest descent method, Newton s law, Powell method, conjugate. DHF completed law: f (x ) = x1 ^ 2+ x2 ^ 2-x1* x2-10* x1-4* x2+ 60.小弟used method of calculation is elected after the iterative expression d be. Were steepest descent method, Newton s law, Powell completed the operation method. Powell method most. Function: Enter the starting point (x0, x1) and accuracy of E obtained the optimal solution.
