The code performs an Inverse distance weighting (IDW) multivariate interpolation, i.e. a process of assigning values to unknown points by using values from usually scattered set of known points.
The code requires vectors of coordinates and variable values of known points (xc,yc,vc) and calculated the variable values by means of Inverse Distance Weighting (IDW) multivariate interpolation for a vector or matrix (Vint) of unknown points described by coordinates (x,y). The code allows to vary the distance weight (e) and to consider a certain number of neighbors through fixed radius or number of neighbours methods.

1.3.0.0

A bug in the fixed radius option has been fixed. The number of neighbours option was always correct. Note that the code requires that the coordinates of the known points must not overlap with the coordinates of the unknown points.
