TSARKIMEXRegister#
register a TSARKIMEX scheme by providing the entries in the Butcher tableau and optionally embedded approximations and interpolation
Synopsis#
#include "petscts.h"   
PetscErrorCode TSARKIMEXRegister(TSARKIMEXType name, PetscInt order, PetscInt s, const PetscReal At[], const PetscReal bt[], const PetscReal ct[], const PetscReal A[], const PetscReal b[], const PetscReal c[], const PetscReal bembedt[], const PetscReal bembed[], PetscInt pinterp, const PetscReal binterpt[], const PetscReal binterp[])
Logically Collective
Input Parameters#
- name - identifier for method 
- order - approximation order of method 
- s - number of stages, this is the dimension of the matrices below 
- At - Butcher table of stage coefficients for stiff part (dimension s*s, row-major) 
- bt - Butcher table for completing the stiff part of the step (dimension s; NULL to use the last row of At) 
- ct - Abscissa of each stiff stage (dimension s, NULL to use row sums of At) 
- A - Non-stiff stage coefficients (dimension s*s, row-major) 
- b - Non-stiff step completion table (dimension s; NULL to use last row of At) 
- c - Non-stiff abscissa (dimension s; NULL to use row sums of A) 
- bembedt - Stiff part of completion table for embedded method (dimension s; NULL if not available) 
- bembed - Non-stiff part of completion table for embedded method (dimension s; NULL to use bembedt if provided) 
- pinterp - Order of the interpolation scheme, equal to the number of columns of binterpt and binterp 
- binterpt - Coefficients of the interpolation formula for the stiff part (dimension s*pinterp) 
- binterp - Coefficients of the interpolation formula for the non-stiff part (dimension s*pinterp; NULL to reuse binterpt) 
Note#
Several TSARKIMEX methods are provided, this function is only needed to create new methods.
