|  | name | - identifier for method | 
|  | order | - approximation order of method | 
|  | s | - number of stages, this is the dimension of the matrices below | 
|  | A | - Table of propagated stage coefficients (dimension s*s, row-major), strictly lower triangular | 
|  | Gamma | - Table of coefficients in implicit stage equations (dimension s*s, row-major), lower triangular with nonzero diagonal | 
|  | b | - Step completion table (dimension s) | 
|  | bembed | - Step completion table for a scheme of order one less (dimension s, NULL if no embedded scheme is available) | 
|  | pinterp | - Order of the interpolation scheme, equal to the number of columns of binterpt | 
|  | binterpt | - Coefficients of the interpolation formula (dimension s*pinterp) |
