Dear all, this is just to verify mainly, it is in my understanding that the sequence of breakpoints is non decreasing (but not strictly), i.e.
\xi_1 <= \xi_2 <= ... <= \xi_n. thus intermediate breakpoints can have some multiplicity (say, if we allow some of them to be equal). Could please someone verify that GSL support this (I see it working - just for me ease of mind)? Many thanks! Foivos
