pytc.df.prepare_normal_equations_solver¶
- pytc.df.prepare_normal_equations_solver(phi_piv_p, phi_piv_q, rcond=1e-14, max_jitter_tries=8, jitter_growth=10.0)[source]¶
Prepare robust Cholesky factor for repeated batched solves.
Uses adaptive jitter escalation to guarantee numerically SPD matrices.
- Parameters:
phi_piv_p (jax.numpy.ndarray)
phi_piv_q (jax.numpy.ndarray)
rcond (float)
max_jitter_tries (int)
jitter_growth (float)
