TSMPRKRegister
register a MPRK scheme by providing the entries in the Butcher tableau
Synopsis
#include "petscts.h"
PetscErrorCode TSMPRKRegister(TSMPRKType name,PetscInt order,
PetscInt sbase,PetscInt ratio1,PetscInt ratio2,
const PetscReal Asb[],const PetscReal bsb[],const PetscReal csb[],const PetscInt rsb[],
const PetscReal Amb[],const PetscReal bmb[],const PetscReal cmb[],const PetscInt rmb[],
const PetscReal Af[],const PetscReal bf[],const PetscReal cf[])
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 in the base methods
|
| ratio1 | - stepsize ratio at 1st level (e.g. slow/medium)
|
| ratio2 | - stepsize ratio at 2nd level (e.g. medium/fast)
|
| Af | - stage coefficients for fast components(dimension s*s, row-major)
|
| bf | - step completion table for fast components(dimension s)
|
| cf | - abscissa for fast components(dimension s)
|
| As | - stage coefficients for slow components(dimension s*s, row-major)
|
| bs | - step completion table for slow components(dimension s)
|
| cs | - abscissa for slow components(dimension s)
|
Notes
Several MPRK methods are provided, this function is only needed to create new methods.
