Detailed Description

template<typename TMatrix>
class ug::ParallelMatrix< TMatrix >

Wrapper for sequential matrices to handle them in parallel.

A ParallelMatrix is a wrapper around a sequential vector to make it usable in parallel. It has all the function a sequential matrix supports, since it is derived from it. Furthermore the ParallelStorageType is remembered. Currently only additive storage type is implemented. In addition some functions of the sequential matrix are overwritten to adapted the functionality to parallel (e.g. set)

Please Note: The Implementation is not yet finished.
