class  Tempus_Test::SteadyQuadraticModel< Scalar >
 Simple quadratic equation with a stable steady-state. This is a simple differential equation

\[ \mathbf{\dot{x}}=\mathbf{x}^2 - b^2 \]

which has steady state solutions $\mathbf{x} = \pm b$. The solution $\mathbf{x} = b$ is stable if $b < 0$ and the solution $\mathbf{x} = -b$ is stable if $b > 0$. This model is used to test pseudo-transient sensitivity analysis methods. More...
