利用AFEPack包求解变二次系数的椭圆型方程.在求解这个问题的过程中，先要把程序的结构进行整理，将变二次项系数的因素加进去 ，并使得其更加有利于复杂一些的问题的求解 。为此，我们使用一个类来管理这个求解的问 题，先写一个对这个类进行声明的头文件 EllipticEquation.h-Use AFEPack package for solving variable coefficient elliptic quadratic equation. In solving this problem, the first to organize the structure of the procedure will change coefficient of quadratic terms added to the list of factors, and make it more conducive to the complexity of some of the problem solving. To this end, we use a class to manage to solve this problem, first write a statement of this type for the header files EllipticEquation.h
