Member Data Documentation

◆ bound_state_filtering

fnft_nsev_opts_t::bound_state_filtering

Controls how fnft_nsev decide whether a numerically found root of \( a(\lambda) \) is an actual bound state or not.
Should be of type fnft_nsev_bsfilt_t.

◆ bound_state_localization

fnft_nsev_opts_t::bound_state_localization

Controls how fnft_nsev localizes bound states.
Should be of type fnft_nsev_bsloc_t.

◆ contspec_type

fnft_nsev_opts_t::contspec_type

Controls how fnft_nsev fills the array contspec.
Should be of type fnft_nsev_cstype_t.

◆ discretization

fnft_nsev_opts_t::discretization

Controls which discretization is applied to the continuous-time Zakharov- Shabat scattering problem. See fnft_nse_discretization_t.

◆ discspec_type

fnft_nsev_opts_t::discspec_type

Controls how fnft_nsev fills the array normconsts_or_residues.
Should be of type fnft_nsev_dstype_t.

◆ Dsub

fnft_nsev_opts_t::Dsub

Controls how many samples are used after subsampling when bound states are localized using the fnft_nsev_bsloc_SUBSAMPLE_AND_REFINE method. See fnft_nsev_bsloc_t for details.

◆ niter

fnft_nsev_opts_t::niter

Number of Newton iterations to be carried out when either the fnft_nsev_bsloc_NEWTON or the fnft_nsev_bsloc_SUBSAMPLE_AND_REFINE method is used.

◆ normalization_flag

fnft_nsev_opts_t::normalization_flag

Controls whether intermediate results during the fast forward scattering step are normalized. This takes a bit longer but sometimes increases the accuracy of the results. By default, normalization is enabled (i.e., the flag is one). To disable, set the flag to zero.
