RustedSciThe 0.4.20

//! Experimental second-generation LSODE-style IVP solver facade.
//!
//! `LSODE2` is intentionally not a patch over the older [`crate::numerical::LSODE`]
//! prototype.  The first milestone reuses the crate's tested BDF implementation
//! as the time-integration engine, while exposing a cleaner configuration surface
//! for the backends that an LSODE-class solver needs:
//!
//! - generated symbolic RHS/Jacobian backends (`Lambdify` / AOT),
//! - dense, sparse, and banded Jacobian/system matrix policies,
//! - production linear solvers from the rest of the crate instead of local
//!   hand-written factorization code.
//!
//! Today this module is a small, working facade around the tested BDF solver.
//! The backend enums are deliberately present from the start so later work can
//! replace the dense-only BDF internals with `faer` sparse and faithful LAPACK
//! banded adapters without changing the user-facing setup shape again.
