LSClogarithmic(Xi,Y​i,Zi,X,Y,Z,C0,D,T,N​,G)

A function to grid residual gravity anomaly data in 3-D space using least squares collocation.

This function can be used to grid residual gravity anomaly data G anywhere in 3 dimensional space using the Forsberg 1987 logarithmic co-variance function.

The required input arguments are the known values, X,Y,Z locations of the gravity observations, the residual gravity signal G, the parameters of the co-varaince function C0 D and T, a vector of estimated variances N (one for each observation O(X,Y,Z,G)) and the locations Xi,Yi,Zi where the signal is desired to be interpolated to.
