Detailed Description

Data class that contains a model's large data, including subspace matrices, trajectories and approximation training data.

Author: Daniel Wirtz

Date: 2011-08-03

Change in 0.6:: (Daniel Wirtz, 2011-12-14) Now also storing the computation time ctime for a trajectory. This comes from the fact that for error estimator comparisons we need the ctime for each trajectory for every different error estimator. See the changes in models.BaseModel for more information.

New in 0.5:: (Daniel Wirtz, 2011-10-20) Added the ATrajectoryData.getBoundingBox method and implementations in MemoryTrajectoryData and FileTrajectoryData.

New in 0.5:

(Daniel Wirtz, 2011-08-03)

Added this class.
Removed the field ApproxfValues and put it into a struct with ApproxTrainData.

This class is part of the framework
