Detailed Description

Implementation for B-spline functions of Laplace Operation, linear grids without boundaries.

Constructor & Destructor Documentation

OperationLaplaceExplicitBspline() [1/2]

sgpp::pde::OperationLaplaceExplicitBspline::OperationLaplaceExplicitBspline	(	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 OperationLaplaceExplicitBspline

Parameters

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

References m.

OperationLaplaceExplicitBspline() [2/2]

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

explicit

Constructor that creates an own matrix i.e.

matrix is destroyed by the destructor of OperationLaplaceExplicitBspline

Parameters

grid	the sparse grid
