MATLAB克里金(Kriging)插值法又称空间自协方差最佳插值法，它是以南非矿业工程师D．G．Krige的名字命名的一种最优内插法。克里金法广泛地应用于地下水模拟、土壤制图等领域，是一种很有用的地质统计格网化方法。( MATLAB kriging (Kriging) interpolation method, also known as spatial autocorrelation covariance optimal interpolation method, which is based on the South African mining engineer D. G. Krige named for an optimal interpolation. Kriging widely used in groundwater modeling, soil mapping, is geostatistical gridding method useful.)
