Member Function Documentation

function Greedy.User.IDetailedData detailed_data = Greedy.Combined.basis_extension	(	Greedy.User.IReducedModel	rmodel,
		Greedy.User.IDetailedData	detailed_data,
			checkpoint
	)

basis extension routine

This method is run by the gen_detailed_data() method at the very end, and shall actually construct the reduced basis.

Parameter values

checkpoint: an object of type Greedy.Checkpoint used for checkpointing.

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.
checkpoint	checkpoint

Return values

detailed_data

object storing the reduced basis information in the leaf nodes and information on the reduced basis generation in every node.

function SnapshotsGenerator.Cached rb_basis_gen = Greedy.Combined.get_ei_basis_generator

(

)

returns the snapshot generator for the reduced basis construction

Return values

rb_basis_gen

snapshot generator

Definition at line 201 of file Combined.m.

function SnapshotsGenerator.Cached rb_basis_gen = Greedy.Combined.get_rb_basis_generator

(

)

returns the snapshot generator for the reduced basis construction

Return values

rb_basis_gen

snapshot generator

function IDetailedData detailed_data = Greedy.Combined.init_basis	(	Greedy.User.IReducedModel	rmodel,
		ModelData	model_data
	)

construction of an initial reduced basis

construction of an initial reduced basis This method is called at the beginning of the gen_detailed_data() method right after a call to prepare(). It should be used to construct an initial reduced basis, e.g. approximating the initial value functions in case of evolution problems.

Parameters

rmodel	object specifying how the reduced simulations can be computed.
model_data	Matlab structure storing (possibly) high dimensional data needed by IDetailedModel.detailed_simulation().

Return values

detailed_data

object storing the reduced basis information in the leaf nodes and information on the reduced basis generation in every node.

Definition at line 100 of file Combined.m.

function Greedy.Combined.prepare ( IReducedModel  rmodel, ModelData  model_data  )

virtual

initialization routine for basis extension

This method is run by the gen_detailed_data() method before the execution of the init_basis() methods and should be used for preparation purposes, like

• initialization of the training and validation parameter space and
• caching detailed simulations if necessary.

Parameters

rmodel	object specifying how the reduced simulations can be computed.
model_data	Matlab structure storing (possibly) high dimensional data needed by IDetailedModel.detailed_simulation().

Implements Greedy.Interface.
