TSIRKTableauCreate

create the tableau for TSIRK and provide the entries

Synopsis

#include "petscts.h"   
PetscErrorCode TSIRKTableauCreate(TS ts, PetscInt nstages, const PetscReal *A, const PetscReal *b, const PetscReal *c, const PetscReal *binterp, const PetscScalar *A_inv, const PetscScalar *A_inv_rowsum, const PetscScalar *I_s)

Not Collective

Input Parameters

• ts - timestepping context

• nstages - number of stages, this is the dimension of the matrices below

• A - stage coefficients (dimension nstages * nstages, row-major)

• b - step completion table (dimension nstages)

• c - abscissa (dimension nstages)

• binterp - coefficients of the interpolation formula (dimension nstages), optional (use NULL to skip)

• A_inv - inverse of A (dimension nstages * nstages, row-major), optional (use NULL to skip)

• A_inv_rowsum - row sum of the inverse of A (dimension nstages), optional (use NULL to skip)

• I_s - identity matrix (dimension nstages * nstages), optional (use NULL to skip)
