摘要
简单介绍了现在常用的空间插值方法,详细介绍曲面插值中的双三次多项式曲面插值和趋势面插值在水文学上的应用;在解高阶矩阵时,用VB调用MatrixVB,利用MatrixVB强大的数学功能,省时省力地计算出矩阵的系数,完成插值的计算。
This article simply introduced the spatial interpolation method commonly used at present and detailedly introduced double three multinomial curved surface interpohfion and trend surface interpohtion in hydrology application. This paper transfers MatrixVB with VB when solution higher order matrix which has formidabh mathematics function, leading to the computation of matrix coefficient easy and timesaving, then the interpolation computation is completed.
