Some of the classes, like DerivativeApproximation, KellyErrorEstimator and SolutionTransfer, act on solutions already obtained, and compute derived quantities in the first two cases, or help transfering a set of vectors from one mesh to another.
The remaining classes MatrixCreator, MatrixTools, and VectorTools provide an assortment of services, such as creating a Laplac matrix, projecting or interpolating a function onto the present finite element space, etc. The difference to the functions in the DoFTools and FETools functions is that they work on vectors (i.e. members of a finite element function space on a given triangulation) or help in the creation of it. On the other hand, the DoFTools functions only act on a given DoFHandler object without reference to a data vector, and the FETools objects generally work with finite element classes but again without any associated data vectors.
