% Kriging Toolbox%¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯%% VARIOGRAMS or STRUCTURE FUNCTIONS (FOR SCALARS):%% vario2dr : variogram(s) of   regular spaced 2-D data% vario2di : variogram(s) of irregular spaced 2-D data% vario3dr : variogram(s) of   regular spaced 3-D data% vario3di : variogram(s) of irregular spaced 3-D data% var2diuv : variogram(s) of irregular spaced 2-D vectors,%            (longitudinal or transverse component)%%   Variograms et correlograms (GSLIB): see the book by%   Deutsch and Journel (1992). Oxford University Press.%   The five (5) variogram functions: vario2dr, vario2di,%   var2diuv, vario3dr and vario3di are m-files calling the%   MEX-files of GSLIB subroutines: GAM2, GAMV2, GAMV2UV, %   GAM3 and GAMV3.%% CONFIDENCE INTERVALS%% confint  : confidence intervals for the structure function% % FITTING VARIOGRAMS:%% fitvario : variogram least-square fitting (optimisation toolbox%     needed)% fun      : function used by 'fitvario' to compute the fonction%            'variogr'% variogr  : computes a set of theoretical correlograms and %            semi-variograms%% KRIGING - COKRIGING (Marcotte, 1991)%% cokri    : performs point or block cokriging in D dimensions% cokri2   : called from cokri; modified for new variograms% means    : similar to mean.m% trans    : called from cokri2%% KRIGING (Davis)%% davis    : punctual Kriging: Davis' method%% FILTERING (Barnes)%% barnes   : makes use of kringing to filter kriged data % filresp  : filter response in the wavelength domain% tintore  : filter gridded data using tintore's parameters%% MISCELLANEOUS UTILITY FUNCTIONS%% deplie   : transform a vector into a matrix% kregrid  : creates a mx2 matrix of all the grid coordinates% ksone    : MEX-file of the normality test % kstest   : Kolmogorov-Smirnov normality test% mat3dp   : pseudo 3-D matrix% mat4dp   : pseudo 4-D matrix% outvario : organization of variogram output variables
