00007 // Description: This file contains the class definition of EigenSOE.
00008 // EigenSOE is a subclass of SystemOfEqn.
00009 // It has pure virtual functions which must be implemented in it's derived
00010 // subclasses. To solve the genreal eigen value equations means that
00011 // by the given K and M, find the corresponding eigen value and eigen
00012 // vectors.
00013 //
00014 // This class is inheritanted from the base class of SystemOfEqn
00015 // which was created by fmk (Frank).
