ButcherPhi
ButcherPhi[tree,s]
gives the weight of tree in an s-stage Runge–Kutta method.
ButcherPhi[tree]
gives the weight of tree in stage-independent tensor notation.
Details and Options
- To use ButcherPhi, you first need to load the Numerical Differential Equation Analysis Package using Needs["NumericalDifferentialEquationAnalysis`"].
- The weight of tree is the left-hand side of the order conditions imposed by tree.
- The following option can be given:
-
RungeKuttaMethod $RungeKuttaMethod type of Runge–Kutta method - Valid settings for RungeKuttaMethod are DiagonallyImplicit, Explicit, and Implicit.
