  1. + Improved: VectorTools::point_difference + used to use an algorithm to find the cell the given point is in that + was linear in the total number of active cells. It has been rewritten + to use + GridTools::find_active_cell_around_point + which is only logarithmic in its complexity. +

    + +
  2. + Fixed: Block matrix iterators could get into all kind of interesting + (and invalid) states when some of the blocks had empty rows. In this + common case, we would frequently skip elements when looping over the + elements of a block matrix. These cases should now be fixed. +
    + (WB 2004/07/07) +

    + +
  3. + Removed: Block matrix iterators used to have a function + it->index() that returned something like + the position within a row. However, this was fragile, and has been + removed. If you want an ordering of elements within a row, use the + operator < to compare iterators. +
