Syntax: @INTERP3D(R, X, Y)
R = a range reference points to x, y and z values of the
vector
X = x values on which the interpolation values are based
Y = y values on which the interpolation values are based
@INTERP3D returns interporlated value for a 3 dimensional vector. X and Y have to be same size.
