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 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.
