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。它首先考虑的是空间属性在空间位置上的变异分布．确定对一个待插点值有影响的距离范围，然后用此范围内的采样点来估计待插点的属性值。该方法在数学上可对所研究的对象提供一种最佳线性无偏估计(某点处的确定值)的方法。它是考虑了信息样品的形状、大小及与待估计块段相互间的空间位置等几何特征以及品位的空间结构之后，为达到线性、无偏和最小估计方差的估计，而对每一个样品赋与一定的系数，最后　进行加权平均来估计块段品位的方法。(Kriging is a technique that provides the Best Linear Unbiased Estimator of the unknown fields (Journel and Huijbregts, 1978 Kitanidis, 1997). It is a local estimator that can provide the interpolation and extrapolation of the originally sparsely sampled data that are assumed to be reasonably characterized by the Intrinsic Statistical Model (ISM). An ISM does not require the quantity of interest to be stationary, i.e. its mean and standard deviation are independent of position, but rather that its covariance function depends on the separation of two data points)

说明：  matlab 实现dbscan 这是一种基于密度的聚类分析算法，可以发现任意形状的簇，可以发现噪声点。(Realization of DBSCAN with MATLAB This is a density based clustering analysis algorithm, which can find clusters of arbitrary shape and noise points.)

该程序能够将matlab中绘制的三维图形，动态化，并最终生成gif文件，原理是使用了getframe()函数，获取几帧图像，再保存为gif文件 (The program can draw matlab in the three-dimensional graphics, dynamic, and ultimately generate the gif file, the principle is the use of getframe () function, to obtain a few frames, and then saved as a gif file)

在Matlab函数,X和y是仪器响应矩阵的列向量和参数值,分别为。Ncal是被选中的对象数目。m所选对象中返回的索引向量。(In this Matlab function, X and y are the instrumental response matrix (independent variables) and the column vector of parameter values (dependent variable), respectively. Ncal is the number of objects to be selected for the calibration set. The indexes of the selected objects are returned in vector m)
