The gray option at the end renders the Mathcad Rkadapt equally spaced.
This final option is obviously needed to export intelligible project,
considering that none of the native Smath ODE solvers has that option
built-in. The proposal could be compacted in the solver itself.
AFAIK [as far as I know], Mathcad 11 and this Smath are same export.
The basic Rkadapt45 is universal for universal CAS.
