Member Function Documentation

void sc::DiagSCMatrix::assign (DiagSCMatrix * d_a) [inline]

Make this have the same elements as m. The dimensions must match.

virtual void sc::DiagSCMatrix::convert (DiagSCMatrix *) [virtual]

Convert an SCDiagSCMatrix of a different specialization to this specialization and possibly accumulate the data.

virtual Ref<SCMatrixSubblockIter> sc::DiagSCMatrix::local_blocks (SCMatrixSubblockIter::Access) [pure virtual]

Returns iterators for the local (rapidly accessible) blocks used in this matrix.

Implemented in sc::BlockedDiagSCMatrix, sc::ReplDiagSCMatrix, sc::DistDiagSCMatrix, and sc::LocalDiagSCMatrix.
