Detailed Description

Block Jacobi preconditioning. See PreconditionBlock for requirements on the matrix. This class satisfies the relaxation concept.

Note: Instantiations for this template are provided for <float> and <double>; others can be generated in application programs (see the section on Template instantiations in the manual).
