|  | name | - identifier for method | 
|  | order | - approximation order of method | 
|  | 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; NULL to use last row of A) | 
|  | c | - abscissa (dimension s; NULL to use row sums of A) | 
|  | 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; NULL to reuse b with p=1) |
