00032 // Description: This file contains the class definition of EigenAnalysis.
00033 // EigenAnalysis is a subclass of Analysis, it is used to perform the
00034 // eigen vlaue analysis on the FE_Model.
00035 //
00036 // This class is inheritanted from the base class of Analysis
00037 // which was created by fmk (Frank).
