00032 // Description: This file contains the class definition for LinearSOESolver.
00033 // LinearSOESolver is an abstract base class and thus no objects of it's type
00034 // can be instantiated. It has pure virtual functions which must be
00035 // implemented in it's derived classes.  Instances of LinearSOESolver are used
00036 // to solve a system of equations.
