TSBasicSymplecticRegister

register a basic symplectic integration scheme by providing the coefficients.

Synopsis

#include "petscts.h"   
PetscErrorCode TSBasicSymplecticRegister(TSRosWType name,PetscInt order,PetscInt s,PetscReal c[],PetscReal d[])
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
c - coefficients for updating generalized position (dimension s)
d - coefficients for updating generalized momentum (dimension s)

Notes

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