说明：  克里金、反距离插值算法_栅格图等值线填充等(Kriging, inverse distance interpolation algorithm _ isogram filled grid map, etc.)

该程序用于瞬变电磁勘探近区场计算，只要输入不同参数便可以得到近区场的视电阻率(The procedure transient electromagnetic exploration for near field calculations, as long as the input parameters can be different near field apparent resistivity)

吉尔算法积分一阶微分方程组初值问题的C语言描述，包括主函数、计算微分方程组中各方程右端函数值的函数程序、计算雅克比矩阵的函数程序、矩阵求逆程序等。(GEAR algorithm integral first order differential equations initial value problem of the C language description, including the main function to calculate the differential equations in the equation right function value function procedures, functions Jacobian matrix calculation procedures, matrix inversion procedures.)

说明：  该程序用有限元方法来处理标量亥姆赫兹方程，其实例是脊形介质波导中的光波。(The functino of the code is to slove Helmholtz equation by using finite element method (FEM). The example is an optical waveguide.)

合成孔径雷达（SAR)目标成像仿真，多姿态，多角度，有不同光照,小波包分析提取振动信号中的特征频率。( Synthetic Aperture Radar (SAR) imaging simulation target, Much posture, multi-angle, have different light, Wavelet packet analysis to extract vibration signal characteristic frequency.)

这是一个三次样条插值函数实现的C代码。如果插值点需要改变，可以在程序中改定。(This is a cubic spline interpolation function of the realization of the C code. If interpolation points need to change, the procedures will change.)

说明：  abaqus周期性边界条件代码，可以参考学习(ABAQUS periodic boundary condition code can refer to learning)

LDL分解法，用于求解大型的线性方程组。此程序中最多能解100维的，速度还不错(LDL decomposition method for solving large-scale linear equations. This procedure can be up to 100 peacekeepers solutions, speed is not bad.)

邻带计算，高斯正反算，可以实现测绘系统内简单的转换计算，但是是基于80坐标系统的。(failed to translate)
