PetscErrorCode TSRKGetTableau(TS ts, PetscInt *s, const PetscReal **A, const PetscReal **b, const PetscReal **c, const PetscReal **bembed, PetscInt *p, const PetscReal **binterp, PetscBool *FSAL)

Not Collective

Input Parameter

• ts - timestepping context

Output Parameters

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

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

• b - step completion table (dimension s)

• c - abscissa (dimension s)

• bembed - completion table for embedded method (dimension s; NULL if not available)

• p - Order of the interpolation scheme, equal to the number of columns of binterp

• binterp - Coefficients of the interpolation formula (dimension s*p)

• FSAL - whether or not the scheme has the First Same As Last property
