Detailed Description

sparse projection operators between grids.

NAME: ProjMatSparse - sparse projection operators between grids

DESCRIPTION:

This projection operator uses a "MatSparse" representation. The "MatSparse" object must be filled by the user.

Constructor & Destructor Documentation

ProjMatSparse::ProjMatSparse ( const char * description_ = "Projecton operator" )

See class "Proj". Notice that a "MatSparse" object must be supplied by use of "rebindMatSparse".

ProjMatSparse::ProjMatSparse ( const Proj_prm & prm,

const char * description_ = "Projection operator" )

See documentation of one of the overloaded constructor.

ProjMatSparse::~ProjMatSparse ( ) [virtual]

Member Function Documentation

String ProjMatSparse::description ( ) const [virtual]

returns the "String" description of the projection operator.
Reimplemented from ProjMatrix.
Reimplemented in ProjInterpSparse, MxProj, and ProjInterpSparseHier.

void ProjMatSparse::print ( Os os,

int output = 1 ) const [virtual]

Reimplemented from ProjMatrix.
Reimplemented in ProjInterpSparse, and MxProj.

bool ProjMatSparse::rebindMatSparse ( MatSparse(NUMT) & m ) [virtual]

connects the projection operator to a "MatSparse" object, i.e., a sparse matrix, which will be used to store the projection.
Reimplemented from Proj.

void ProjMatSparse::scale ( real s ) [virtual]

See documentation of one of the overloaded functions.
Reimplemented from ProjMatrix.

void ProjMatSparse::scale ( const LinEqVector & s,

TransposeMode tpmode ) [virtual]

scales the projection operator according to input values. If the a scalar constant "s" is applied, all entries in the operator is scaled by the constant value, "P(i,j)=s*P(i,j)".
If the input sepcifies a "LinEqVector", the operator is scaled row- or columnwise. That is, for "tpmode=TRANSPOSED" the rows are scaled, "P(i,j) = s(i)*P(i,j)". Similarly, for "tpmode=NOT_TRANSPOSED" the wolumns are scaled as "P(i,j)=s(j)*P(i,j)".
Reimplemented from ProjMatrix.
