最优化理论与方法，其中包括两种BFGS算法与共轭梯度法，以及H终止准则！！1,Optimization theory and methods, including the two co-BFGS algorithm for conjugate gradient method, as well as the termination criteria for H! ! 1

本代码为《最优化理论与方法》书籍中的牛顿法和拟牛顿法算法的代码，并举了2个书上的作业题的例子，本代码中的目标函数和约束等初值可由需要进行改变，来得到所期望的计算-The code for the " optimization theory and method" books in the Newton method and quasi-Newton method algorithm code, citing two books on the example of the job

最优化理论，利用最优化理论中的BFGS法来得到方程的最优解(Optimization theory, using the BFGS method in optimization theory to obtain the optimal solution of the equation)
