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 title, the code in the objective function and constraints may need to change the initial value to obtain the desired calculation
