+## Every elements in @var{f} corresponds to a data point (observation)

+## @var{lenx} is correlation length in x-direction.

+## @var{xi} is the data points where the field is

+## its error variance.
+##
+## The background field of the optimal interpolation is zero.
+## For a different background field, the background field
+## must be subtracted from the observation, the difference 
+## is mapped by OI onto the background grid and finally the
