Rosenbrock methods

The Rosenbrock methods are a family of numerical techniques used for solving ordinary differential equations (ODEs) and are particularly well-suited for stiff problems. They are named after Howard H. Rosenbrock, who developed them in the context of numerical analysis. ### Key Features of Rosenbrock Methods: 1. **Semi-implicit Scheme**: The Rosenbrock methods are semi-implicit in nature, meaning they combine explicit and implicit steps.
