[Help-gsl] Question on Bsplines knot multiplicity

[Foivos Diakogiannis]

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!
