Detailed Description

template<class Scalar>
class Tempus_Test::DahlquistTestModel< Scalar >

The classic Dahlquist Test Problem.

This is the canonical Dahlquist test equation

$\mathbf{\dot{x}} = \lambda \mathbf{x}.$

where $\lambda \in \mathbf{C}$ with the initial condition $\mathbf{x}(0) = 1$ . The exact solution is

$\mathbf{x}(t) = \exp{\lambda t}.$

When $\mathbf{R}(\lambda) < 0$ , $\mathbf{x} \rightarrow 0$ as $t \rightarrow \infty$ . Numerical methods that exhibit this property are said to be A-stable.
