Hi there
I am not familiar with the EOF analysis, but I guess it has something
to do with a decomposition technique with many names in different
research
communities: Karhunen-Loeve decomposition, Proper Orthogonal
Decomposition,
Bi Orthogonal Decomposition and finally the Singular Value
Decomposition.
There is an idl routine called svdc based on the Numerical Recipes, thus
you will find some documentation both in the online help system and the
book "Numerical Recipes in *"
A long shot, but hopefully this is what you are looking for.
