分别用梯形法和矩形法求定积分，附加应用实例(, Respectively, with the trapezoidal method and the rectangle method to find definite integrals, additional application examples)

用C++来实现NEWTON迭代法解非线性方程算法数值分析，是数值分析里典型的一个算法。(In C++ to achieve NEWTON iterative numerical algorithm for solving nonlinear equations, numerical analysis is in a typical algorithm.)

有限元n维实体材料单元，仅供科研用途，拒绝商业使用(N-dimensional finite element solid material element, for scientific purposes, refusing commercial use)

2维的FDTD C程序(2-dimensional FDTD C procedures)

多物理场耦合软件采用有限元方法模拟rtfindgen(Coupled multi-physics simulation software using the finite element method rtfindgen)

计算方法《牛顿差值》(calculation method, "Newton margin")

比Windows自带的高级一点的计算器，能将整个表达式输入，然后求值。 这个程序要求读者具备编译原理的一些知识。 (Advanced calculator than Windows built, the whole expression input can be then evaluated. This program requires the reader to have some knowledge of compiler theory.)

它是一个计算热通量的c++程序，用udf导入fluent，既可以求解，非常好用的一个，可以作为入门的一个例子学习。(it is a calculated heat flux of c++ program, with udf into fluent, not only can solve, very easy to use one, can be used as a case study entry.)

说明：  c++语言求解稀疏矩阵方程组的ICCG法源程序。参考：《工程电磁场数值计算分析与综合》 附录（Fortran90）.(c++ solves sparse matrix equations with the ICCG method.Reference: &quot Analysis and Synthesis of Numerical Electromagnetic Field ,&quot Appendix (Fortran90).)

说明：  埃特金不等距插值，有例子，检验过，很顺利(Aitken non-equidistant interpolation, there are examples of tests, it is smooth)
