Re: Matrix problems

Hi Ashton,

one of the more common reasons for this is that two locations
in the data, or a data location and a grid node coincide or
(and this is harder to detect) almost coincide. The first
possibility is easily found, by adding `average' to the
data definition. This options averages duplicate points
in a data file.

Summer's back!
