Specific improvements

    + +
  1. Improved: The iterator class of the deal.II SparseMatrix class +and SparsityPattern have been revised for performance. Iterating over +a row of the matrix and querying the column index and the value is now +similarly fast as iterating over a vector. +
    +(Martin Kronbichler, 2013/02/12) +
  2. New: A new overload of BlockMatrixBase::add allows to add one block matrix to another, with a scaling factor.
