I did (a) on the weekend as well, could call it a weekend. But I will
have a look at (b) soon.
Right now, I am trying to find out what actually might be useful for GSL
and what I have to pay attention to.

For the actual problem, *monotone spline interpolation*, there are three
different solutions known to me:
(a) M.Steffen, "A simple method for monotonic interpolation in one
dimension", Astron. Astrophys. 239, 443-450 (1990).
(b) H.T.Huynh, "Accurate Monotone Cubic Interpolation", SIAM J. Numer. Anal.
30, 57-100 (1993).
(c) Fritsch, F. N.; Carlson, R. E., "Monotone Piecewise Cubic
Interpolation", SIAM J. Numer. Anal. 17 (2), 238–246 (1980).
If you had to pick one of (a) or (b) to try first, I'd try (b). If
it's satisfactory, call it a day.
