Detailed Description

An implementation of the Prober interface that operates on Epetra matrices and linear systems.

The Prober currently works only on structurally symmetric problems. Support for structually non-symmetric problems is under development.

Constructor & Destructor Documentation

Isorropia::Epetra::Prober::Prober	(	Teuchos::RCP< const Epetra_CrsGraph >	input_graph,
		const Teuchos::ParameterList &	paramlist,
		bool	compute_now = true
	)

Constructor.

Parameters:

[in]	input_graph	the graph whose sparsity pattern is to guide the probing.
[in]	paramlist	this parameter list may be used to pass parameters to the colorer.
[in]	compute_now	if true, the coloring is computed in the constructor, otherwise call Isorropia::Epetra::Prober::color when you want to compute the coloring, defaults to false

Isorropia::Epetra::Prober::Prober	(	Teuchos::RCP< const Epetra_CrsMatrix >	input_matrix,

	)

Constructor.

Parameters:

[in]	input_matrix	the matrix whose sparsity pattern is to guide the probing.
[in]	paramlist	this parameter list may be used to pass parameters to the colorer.
[in]	compute_now	if true, the coloring is computed in the constructor, otherwise call Isorropia::Epetra::Prober::color when you want to compute the coloring, defaults to true
