说明：  运筹学中的运输问题的C++程序，支持产销平衡与产销不平衡，可以判断解的情况。(C++ code of transportation problem)

该程序用fortran90编写，时域有限差分（FDTD)中的分裂场方法。解决了斜入射情况下周期结构的电磁散射问题。(FORTRAN90 prepared with the program, finite difference time domain (FDTD) method of splitting the market. Solved the case of oblique incidence of electromagnetic scattering from periodic structure issues.)

共轭梯度法（Conjugate Gradient）是介于最速下降法与牛顿法之间的一个方法，它仅需利用一阶导数信息，但克服了最速下降法收敛慢的缺点，又避免了牛顿法需要存储和计算Hesse矩阵并求逆的缺点，共轭梯度法不仅是解决大型线性方程组最有用的方法之一，也是解大型非线性最优化最有效的算法之一(Conjugate gradient method (Conjugate Gradient) is between the steepest descent method and Newton' s method between a method that takes only a first derivative information, but to overcome the slow convergence of the steepest descent method shortcomings, but also avoid the need to store Newton and computing the inverse Hesse matrix and disadvantages, conjugate gradient method is not only to solve large linear equations of the most useful methods, large-scale nonlinear optimization solution is the most efficient algorithms)
