  1. New: When Hypre is available as a sub-package of PETSc, the new class + PETScWrappers::PreconditionBoomerAMG provides the BoomerAMG implementation + of the algebraic multigrid method of the Hypre package as a preconditioner. + This functionality is used, for example, in step-40. +
    + (Timo Heister 2010/11/13) +

  2. New: The class LAPACKFullMatrix now has functions to compute the singular value decomposition of a matrix and its inverse.
