Detailed Description

template<class T, template< class > class MatrixImpl>
class AMDiS::MatrixFacade< T, MatrixImpl >

Basis implementation of DOFMatrix, i.e. a sparse matrix storing all the assembled Operators indexed with DOF indices. The matrix data is associated to a row and column global basis.

Template Parameters
TThe coefficient type of the matrix
MatrixImplA linear-algebra backend for the matrix storage

Constructor & Destructor Documentation

◆ MatrixFacade()

MatrixFacade ( RowBasis const &  rowBasis,
ColBasis const &  colBasis 

Constructor. Forwards the bases to the implementation class and constructs a matrix sparsity pattern.

Member Function Documentation

◆ scatter()

void scatter ( RowLocalView const &  r,
ColLocalView const &  c,
LocalMatrix const &  localMatrix 

Insert a block of values into the sparse matrix (add to existing values) The global matrix indices are determined by the corresponding localviews.
