Detailed Description

template<class Scalar>
class Tempus::StepperDIRK_1Stage1stOrderRadauIA< Scalar >

RK Implicit 1 Stage 1st order Radau IA.

The tableau (order = 1) is

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

and is A-stable. Reference: Solving Ordinary Differential Equations II: Stiff and Differential-Algebraic Problems, 2nd Revised Edition, E. Hairer and G. Wanner, Table 5.3, pg 73.

See StepperDIRK for additional details.
