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

T	The coefficient type of the matrix
MatrixImpl	A linear-algebra backend for the matrix storage

Constructor & Destructor Documentation

◆ MatrixFacade()

MatrixFacade	(	RowBasis const &	rowBasis,
		ColBasis const &	colBasis
	)

inline

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
	)

inline

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