## 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
