抛物方程是由赫姆霍兹方程推导而来，在计算大区域电磁传播有较大的优势，本程序是二维的情况。(Parabolic equation is derived the Herm Holtz equation, in the calculation of large areas of electromagnetic propagation has a greater advantage, the program is a two-dimensional situation.)

用C++编的一些最优化作业中的程序,有Newton法,DFP法,共轭梯度法,单纯形法,内点法,外点法,内外点法,都能使用,我已经全部调试过了(C compile some of the most optimized operating procedures, Newton, DFP, conjugate gradient method, the simplex method, interior point method, the points outside the law, outside point method can use, I have all over Debugging)

这个我写的一个计算LC滤波器的程序，可以显示出最后的频率截止情况，有最平法，椭圆法等计算方法(this, I wrote a calculation of the LC filter procedures can demonstrate that the frequency of the final deadline, the most-France, oval law calculation method)

编程序，按如下要求来求解n元一次线性方程组（假设方程组具有唯一解）。 （1）方程个数n之值由用户通过键盘输入； （2）方程组存放在“增广矩阵”A之中，而n行n+1列的A存储空间通过new来动态分配，且A的各元素值也由用户通过键盘输入 (Allocation procedures, the following requirements to solve the n-a system of linear equations (assuming a unique solution of equations). (1) the number n of the value equation by the user through the keyboard input (2) equations stored in the augmented matrix A, while n line n+ 1 column A storage space through the new dynamically allocated, and A The value of each element by the user through the keyboard input)
