dimension


Prescribe the number of active dimensions

Specification

Alias: none

Argument(s): 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
    actual_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.
