包括基本的克里金(Kriging)插值法实现代码，仅实现基本方法部分，不包含扩展克里金方法( kriging uses ordinary kriging to interpolate a variable z measured at locations with the coordinates x and y at unsampled locations xi, yi. The function requires the variable vstruct that contains all necessary information on the variogram. vstruct is the forth output argument of the function variogramfit. This is a rudimentary, but easy to use function to perform a simple kriging interpolation. I call it rudimentary since it always includes ALL observations to estimate values at unsampled locations. This may not be necessary when sample locations are not within the autocorrelation range but would require something like a k nearest neighbor search algorithm or something similar. Thus, the algorithms works best for relatively small numbers of observations (100-500). For larger numbers of observations I recommend the use of GSTAT. Note that kriging fails if there are two or more observa)

替代数据方法（基于相位随机化方法），检验续写的非线性(Surrogate data method (based on random-phase method), non-linear write test)

可进行最小二乘法线性拟合输出，包含源代码及生成后的程序(Least-squares linear fit can be output)

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.)

此程序为基于时域有限差分法的matlab程序，主要是计算二维MUR吸收方柱散射(This procedure is based on finite difference time domain method matlab program, mainly of two-dimensional scattering MUR absorbing square columns)

matlab求解变系数双曲方程，使用迎风格式(matlab solves the hypolic equation using upwind method)
