00007 // Description: This file contains the class definition of EigenSOE.
00008 // EigenSOE is a subclass of Solver.
00009 // This is an abstract base class and thus no objects of it's type
00010 // can be instantiated. Instances of EigenSolver are used to solve
00011 // a EigenSOE. (perform eigen analysis)
00012 //
00013 // This class is inheritanted from the base class of Solver
00014 // which was created by fmk (Frank).
