convolution

通过C++头文件实现的有限元形状函数计算程序(finite element shape function)

C++程序求两点距离 可以点入坐标点(C++ program distance between two points)

开发环境没有可选项，fortran90,Fortran_90_and_Computational_Science-_codes(Computational Science codes by fortran90 )

用来计算航天器再入质点弹道，其中包括插值算法，龙格库塔法以及大气模型(Used to calculate the particle trajectory of spacecraft re-entry, including the interpolation algorithm, Runge-Kutta method as well as atmospheric model)

天线组阵中相位差的递推最小二乘估计与滤波(Phase array antenna group recursive least squares estimation and filtering)

说明：  Neville插值算法，xa为自变量数组，xy为因变量数组；x为待插值的自变量(Neville interpolation algorithm, xa array as variables, xy array as the dependent variable x for the independent variables to be interpolated)

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.)
