  1. Improved: The class SolverCG can + now estimate the condition number of the linear system using TridiagonalMatrix and LAPACK. +
    + (GK 2006/09/06) +

    + +
  2. New: the class TridiagonalMatrix + has been introduced together with its basic methods, including an + eigenvalue solver for the symmetric case (LAPACK). +
    + (GK 2006/09/06) +

  3. Improved: PETSc 2.3.1 (build 16) is now supported by the linear preconditioner classes. The new PETSc functions PCFactorSetXXX are used.
