30// CreateTridi populates an empty EpetraCrsMatrix with a tridiagonal with
31// -1 on the off-diagonals and 2 on the diagonal.
32//
33// CreateTridiPlus creates the same matrix as CreateTridi except that it adds
34// -1 in the two off diagonal corners.
35//
36// This code was plaguerized from epetra/example/petra_power_method/cxx_main.cpp
37// presumably written by Mike Heroux.
