Description: 上述算法的终止准则为H终止准则。要求编写通用程序。
关于函数的要求：
直线搜索所计算的函数自己任选。
共轭梯度法所计算的函数：①计算一个正定二次函数（至少是4元函数）；②至少计算一个非二次函数（至少是5元函数）。
非线性最小二乘问题的修正Gauss-Newton法所计算的函数：至少计算一个非线性函数（至少是5元函数）。
乘子法所计算的问题：等式约束、不等式约束要求至少各有一个。问题可在教材或其它参考书中任意选取。
程序自行编写（禁止采用调用现成软件的方式），编程语言自选。
-above algorithm criteria for the termination of H termination criteria. Requests for common procedures. The demands on function : linear search function by calculating their options. The conjugate gradient method by calculating function : calculate a definite quadratic function (at least four yuan function); calculated at least one non-quadratic function (at least five yuan functions). The nonlinear least squares problems that Gauss-Newton method by calculating function : at least a nonlinear function computing (at least five yuan functions). Multiplier Method calculation problem : identity bound inequality constraints have required at least one. Problems in reference books or other materials were selected at random. Self-preparation procedure (called ban on the use of existing software)

Description: 这个c++程序用于求解形如
-(pu')'+qu=f；u=0于左边界；u'=alpha于右边界。
的椭圆型偏微分方程。采用有限元解法，二次元差分格式。
使用说明：
在corefunc.h中自己定义修改方程中的函数p,q,f，它们分别对应文件中的3个函数funcp,funcq,funcf。
核心函数是double *Calcu(double *x, int n,double alpha=0.0)
其中x是节点数组，n+1应等于节点数量。alpha是右边值条件。核心函数返回计算的
近似解u在节点及对偶节点上的函数值。(A function for finite element experiment.)
