Prescribe the number of active dimensions
Alias: none
Argument(s): INTEGER
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
dimensions, where
is assigned by dimension.
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.
