### Input Parameters

| 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 | - wheather or not the scheme has the First Same As Last property
