A virtual class that simplifies the construction of custom operators.
This class takes a blocked linear op and represents it in a flattened form.
virtual VectorSpace domain() const
Domain space of this operator.
Teuchos::RCP< const BlockReorderManager > getReorderManager() const
Get accessor to make reuse easier.
virtual void implicitApply(const MultiVector &x, MultiVector &y, const double alpha=1.0, const double beta=0.0) const
Perform a matrix vector multiply with this implicitly defined blocked operator.
Teko::ModifiableLinearOp getBlockedOp() const
Get accessor to make reuse easier.
virtual VectorSpace range() const
Range space of this operator.
