Detailed Description

template<typename Scalar>
class Tempus::StepperTrapezoidalTimeDerivative< Scalar >

Time-derivative interface for Trapezoidal method.

Given the state $x$, compute the Trapezoidal method time-derivative,

\[ \dot{x}_{n} = \frac{(x_{n} - x_{n-1})}{(\Delta t_n/2)} - \dot{x}_{n-1}. \]

$\ddot{x}$ is not used and set to null.
