I thought about using the EigenRowMajorSparseMatrix or IstlRowMajorSparseMatrix, but I did not see a possibility to create one of these from the FieldMatrix (there is only a constructor from BackendType, which is not FieldMatrix (?)), so I decided to do a quick and dirty implementation on my own. If you point me to the constructors from a FieldMatrix, I could just use one of these internally (or templatize Affine by the MatrixType?). "}}
