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)

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.)

Visual C++6.0 实现的多功能计算器(Visual C++6.0 achieve the multi-function calculator)

稀疏脉冲反褶积代码,包括高尔消元法解矩阵方程阻,自相关,互相关,褶积,反褶积的代码. 刚参加工作那会儿,上进心也足,爱动脑,编了很多的程序,唯有这一个是我引以为傲的,花了几个星期写的稀疏脉冲(预测)反褶积的代码,放到了现在,觉得也没必要再私藏下去了,不出五年,我都不知道这段代码是干什么的了. 希望对大家有用,方法太简单,所以效果不是太好,请大家修改,如要转载,请记得注明出处. (vc++)
