Detailed Description

template<typename VectorType>
class MGMatrixBase< VectorType >

Multilevel matrix base. This class sets up the interface needed by multilevel algorithms. It has no relation to the actual matrix type and takes the vector class as only template argument.

Usually, the derived class mg::Matrix, which operates on an MGLevelObject of matrices, will be sufficient for applications.
