Detailed Description
Configuration for seeded random Fourier feature stimulus fields.
Member Data Documentation
◆ amplitude
| double SimStimulusRandomFourierConfig::amplitude |
Overall amplitude scale.
◆ coord
| SimStimulusCoordConfig SimStimulusRandomFourierConfig::coord |
Spatial coordinate mapping configuration.
◆ feature_count
| unsigned int SimStimulusRandomFourierConfig::feature_count |
Number of random Fourier features.
◆ field_index
| size_t SimStimulusRandomFourierConfig::field_index |
Target field index.
◆ fixed_clock
| bool SimStimulusRandomFourierConfig::fixed_clock |
Lock evolution to nominal_dt instead of adaptive dt.
◆ k_max
| double SimStimulusRandomFourierConfig::k_max |
Maximum spatial wavenumber (rad / unit).
◆ k_min
| double SimStimulusRandomFourierConfig::k_min |
Minimum spatial wavenumber (rad / unit).
◆ kx
| double SimStimulusRandomFourierConfig::kx |
Optional base wavevector X component (rad / unit).
◆ ky
| double SimStimulusRandomFourierConfig::ky |
Optional base wavevector Y component (rad / unit).
◆ nominal_dt
| double SimStimulusRandomFourierConfig::nominal_dt |
Nominal dt when fixed_clock is enabled.
◆ omega
| double SimStimulusRandomFourierConfig::omega |
Temporal angular frequency Ω (rad / s).
◆ scale_by_dt
| bool SimStimulusRandomFourierConfig::scale_by_dt |
Scale writes by dt when true; else dt-independent.
◆ seed
| uint64_t SimStimulusRandomFourierConfig::seed |
RNG seed for reproducible features.
◆ spectral_slope
| double SimStimulusRandomFourierConfig::spectral_slope |
Spectral slope exponent β with target PSD ∝ |k|^{-β}.
◆ time_offset
| double SimStimulusRandomFourierConfig::time_offset |
Additional time shift applied before evaluation.
◆ use_wavevector
| bool SimStimulusRandomFourierConfig::use_wavevector |
Use (kx,ky)-projected features instead of coord mapping.
