PZ: An object oriented environment for scientific programming

An object oriented environment for scientific programming is presented. The environment includes classes for matrix computations (Tmatrix) and a set of classes for the implementation of finite element algorithms (PZ). The PZ environment implements one and two dimensional finite elements with arbitrary orders of interpolation and applicable to a variety of systems of differential equations. The TMatrix environment includes an abstract matrix class interface and a variety of storage patterns and solution methods.
