Function Documentation

function reduced_data_subset = nonlin_evol_reduced_data_subset	(		model,
			reduced_data
	)

method which modifies reduced_data, which is the data, that will be passed to the online-simulation algorithm.

Typically, this routine only does a submatrix extraction of the reduced_data.M, reduced_data.N sized offline-objects to produce model.M, model.N sized objects for the real simulation.

Parameters

model	model
reduced_data	reduced data

Return values
