Detailed Description

template<class Scalar>
class Tempus::StepperERK_Trapezoidal< Scalar >

RK Explicit Trapezoidal.

The tableau (order=2) is

\[ \begin{array}{c|c} c & A \\ \hline & b^T \end{array} \;\;\;\;\mbox{ where }\;\;\;\; \begin{array}{c|cc} 0 & 0 & \\ 1 & 1 & 0 \\ \hline & 1/2 & 1/2 \\ & 3/4 & 1/4 \end{array} \]
