Constructor & Destructor Documentation

NonlinEvol.RbReducedDataNode.RbReducedDataNode	(	NonlinEvol.ReducedModel	rmodel,
		IDetailedData	detailed_data
	)

constructor for the generation of the reduced data.

Alternative synopsis: RbReducedDataNode(rmodel, ei_reduced_data_node)

copying a reduced data node and (optionally) extracting smaller matrices.

Parameters

rmodel	object specifying how the reduced simulations can be computed.
detailed_data	object defining the basis generation algorithm and storage for storing high dimensional data, i.e. dependent on dimension \(H\). This data is necessary for detailed simulations, construction of online matrices, `reduced_data` and reconstruction of reduced simulations.
