Detailed Description

Template for the SOR_a preconditioners by K. Johannsen for SparseMatrix<T> -matrices.

This version uses the lexicographical ordering of the grid points. This preconditioner is efficient for non-symmetric problems.

The templates depend on a type T. This type should satisfy the conditions listed in 'small_matrix.hpp' for small matrices.
