◆ assembleGlobalBasisTransferMatrix()

template<class MatrixType , class CoarseBasis , class FineBasis >
static void assembleGlobalBasisTransferMatrix ( MatrixType &  matrix,
const CoarseBasis &  coarseBasis,
const FineBasis &  fineBasis,
const double  tolerance = 1e-12 
)
static

Assemble the transfer matrix for multigrid methods.

The coarse and fine basis has to be related: in a way that the fine grid is descendant of the coarse grid (not necessarily direct descandant). The two bases are assumed to implement the dune-functions basis interface.

Parameters
[out]matrixthe matrix corresponding to the basis transfer operator
[in]coarseBasisglobal basis on the coarse grid
[in]fineBasisglobal basis on the fine grid
[in]tolerance(optional) interpolation threshold. Default is 1e-12.
