Only if "huge" = 3x3 :)  (in vtkMath::Diag---)

VTK concentrates on visualization and not numerical linear algebra.  There have
been past threads on this mailing list that tossed around the idea of
incorporating LA pkgs into VTK (e.g., search for "svd"), but to my knowledge
nothing is in the planning stage.
