dimension

Prescribe the number of active dimensions

Specification

• Alias: None

• Arguments: INTEGER

Description

If a prescribed dimension for the rotation matrix is desired, this can be specified with the keywork dimension. In this case, the algorithm does not use the truncation_method or the truncation_tolerance to determine the truncation of the rotation matrix, but it just selects the first \(d\) dimensions, where \(d\) is assigned by dimension.

Examples

The following block

model
  id_model = 'SUBSPACE'
  adapted_basis
    truth_model_pointer = 'FULLSPACE'
    sparse_grid_level = 1
    dimension = 3

prescribes the selection of the first three most important directions to build the rotation matrix and the reduced model representation.
