Member Function Documentation

initialize()

void PreconditionChebyshev< MatrixType, VectorType >::initialize	(	const SparseMatrix &	matrix,
		const AdditionalData &	additional_data = AdditionalData()
	)

Initialize function. Takes the matrix which is used to form the preconditioner, and additional flags if there are any.
