Detailed Description

template<class Scalar>
class Tempus::StepperERK_ForwardEuler< Scalar >

Forward Euler Runge-Kutta Butcher Tableau.

The tableau for Forward Euler (order=1) is

\[ \begin{array}{c|c} c & A \\ \hline & b^T \end{array} \;\;\;\;\mbox{ where }\;\;\;\; \begin{array}{c|c} 0 & 0 \\ \hline & 1 \end{array} \]

See StepperExplicitRK for additional details.
