Last change on this file since 11679 was 11679, checked in by Eric.Larour, 13 years ago

Large commit, to strip out Petsc from the code. Created new Matrix and Vector
wrapper objects to the Petsc Mat and Vec objects. These wrappers make it possible
to hook up a different package to handle matrix and vector operations.

2 * \brief container for information needed to plug element matrix generated by elements
3 * into the Kff and Kfs global matrices.
4 * This object will hold the element matrix on the g-set, the local as well as global
5 * dof lists in the f and s sets.
