Member Function Documentation

LinearOp Teko::IdentityPreconditionerFactory::buildPreconditionerOperator	(	LinearOp &	lo,
		PreconditionerState &	state
	)		const [virtual]

Create the Identity preconditioner operator.

This method breaks apart the BlockLinearOp and builds a block diagonal preconditioner. The inverse of the diagonals are specified by the BlockInvDiagonalStrategy object.

Implements Teko::PreconditionerFactory.
