#![cfg(test)]

//! Checked-in generated fixtures for the parameterized IVP AOT slice.
//!
//! Example system:
//! - `f0(t, y, z, a, b, c) = a*t + y + b*z`
//! - `f1(t, y, z, a, b, c) = c*y - z + b*t`
//!
//! Jacobian is taken only with respect to `[y, z]`.
//!
//! Flattened argument order:
//! - `t`
//! - `a`
//! - `b`
//! - `c`
//! - `y`
//! - `z`
