    x_hat_psi: Vec<f64>,

Expand description

Persistent GAMP state carried across linearization iterations.

Fields§

§x_hat_meas: Vec<f64>§tau_x_meas: f64§s_hat_meas: Vec<Complex64>§x_hat_psi: Vec<f64>§p_hat_psi: Vec<f64>§tau_x_hat_psi: f64§tau_p_psi: f64§damp: f64

CURRENT damping factor for the signal updates. Starts at the configured damp_rate_sig and is only ever reduced when a sweep is found to have made the data fit worse (see the adaptive-damping note on gamp_awgn), then relaxed back towards the configured value. On data where nothing diverges it never leaves the configured value, so the iteration is bit-for-bit what it was before.

§damp_ceiling: f64

Ceiling that damp may relax back up to. RATCHETS DOWN on every rejected sweep: once a run has shown it diverges at a given damping, letting the damping climb back to that value simply re-diverges. Without this the guard catches each blow-up but the iteration keeps re-entering the divergent regime and the result is still unusable.
