Constructor & Destructor Documentation

OperationMatrixLTwoDotExplicitBspline() [1/2]

sgpp::pde::OperationMatrixLTwoDotExplicitBspline::OperationMatrixLTwoDotExplicitBspline	(	sgpp::base::DataMatrix *	m,
		sgpp::base::Grid *	grid
	)

Constructor that uses a external matrix pointer to construct the matrix, i.e.

matrix is NOT destroyed by the destructor of OperationMatrixLTwoDotExplicitBsplineFullGrid

Parameters

m	pointer to datamatrix of size (number of grid point) x (number of grid points)
grid	the sparse grid

References grid(), and m.

OperationMatrixLTwoDotExplicitBspline() [2/2]

sgpp::pde::OperationMatrixLTwoDotExplicitBspline::OperationMatrixLTwoDotExplicitBspline ( sgpp::base::Grid *  grid )

explicit

Constructor that creates an own matrix i.e.

matrix is destroyed by the destructor of OperationMatrixLTwoDotExplicitBsplineFullGrid

Parameters

grid	the sparse grid

References grid().

~OperationMatrixLTwoDotExplicitBspline()

sgpp::pde::OperationMatrixLTwoDotExplicitBspline::~OperationMatrixLTwoDotExplicitBspline ( )

virtual

Destructor.
