TSRosWRegister

register a Rosenbrock W scheme by providing the entries in the Butcher tableau and optionally embedded approximations and interpolation

Synopsis

#include "petscts.h"   
PetscErrorCode TSRosWRegister(TSRosWType name,PetscInt order,PetscInt s,const PetscReal A[],const PetscReal Gamma[],const PetscReal b[],const PetscReal bembed[],
                              PetscInt pinterp,const PetscReal binterpt[])
Not Collective, but the same schemes should be registered on all processes on which they will be used

Input Parameters

name - identifier for method
order - approximation order of method
s - number of stages, this is the dimension of the matrices below
A - Table of propagated stage coefficients (dimension s*s, row-major), strictly lower triangular
Gamma - Table of coefficients in implicit stage equations (dimension s*s, row-major), lower triangular with nonzero diagonal
b - Step completion table (dimension s)
bembed - Step completion table for a scheme of order one less (dimension s, NULL if no embedded scheme is available)
pinterp - Order of the interpolation scheme, equal to the number of columns of binterpt
binterpt - Coefficients of the interpolation formula (dimension s*pinterp)

Notes

Several Rosenbrock W methods are provided, this function is only needed to create new methods.
