Function analytical_step_jacobians 

pub fn analytical_step_jacobians(model: &Model, state: &State) -> StepJacobians

👎Deprecated since 0.1.0:

this is not analytical — the ABA block uses finite differences; use semi_implicit_step_jacobians, or symbolic::symbolic_step_jacobians for exact derivatives

Deprecated alias for semi_implicit_step_jacobians.

The old name claimed the result was analytical; the ABA block is computed by finite differences.
