DBMatOnlineDE * sgpp::datadriven::DBMatOnlineDEFactory::buildDBMatOnlineDE	(	DBMatOffline &	offline,
		Grid &	grid,

		double	beta = 0
	)

Factory to build a DBMatOnlineDE object to manipulate the decomposition in offline object.

Parameters

offline	offline object that holds the decomposed system matrix
grid	the underlying grid
lambda	regularization strength (todo(fuchsgruber): maybe remove this)
beta	plasticity weighting factor. If set to 0, no plasticity takes place.
