00032 // Description: This file contains the class definition of EigenAlgorithm.
00033 // EigenAlgorithm is a class which performs a eigen solution algorithm
00034 // to solve the equations.
00035 //
00036 // This class is inheritanted from the base class of SolutionAlgorithm
00037 // which was created by fmk (Frank).
