Constructor & Destructor Documentation

SnapshotsGenerator.Trajectories.Trajectories	(	IDetailedModel	dmodel,
			id,
			force_delete,
			enable_caching
	)

constructor for a snapshot generator creating trajectories of DOF vectors by a IDetailedModel.detailed_simulation() call.

Parameters

dmodel	object specifying how the high dimensional data can be computed.
id	a unique string identifier for this object.
force_delete	boolean value indicating whether the cached data shall be automatically deleted if its inconsistent with the given `dmodel`. (Default = `true`)
enable_caching	boolean value indicating whether the generated data shall be stored in a cache. (Default = `true`)

function [U , opt_fields ] = SnapshotsGenerator.Trajectories.generate_impl	(	IDetailedModel	dmodel,
		IDetailedData	detailed_data,
			fields
	)

protectedvirtual

generates a sample trajectory or detailed simulation item from which a new basis function can be generated.

Parameters

fields	cell array of structure field names which shall also be stored in the cache in the `opt_fields` structure. If not given only the `U` is generated.
dmodel	object specifying how the high dimensional data 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.

Return values

U	a matrix with DOF vector columns holding the generated snapshots.
opt_fields	optional fields to be cached.
