Re: [Help-gsl] Bspline fitting--problem with derivatives

[Caterina Michelagnoli]

Thanks Rhys,

at the end I managed in solving the problem. 

Now I would like to get the derivative but it
seems not to like bspline_deriv and similar:

it gives 

error: ‘gsl_bspline_deriv_workspace’ was not declared in this scope

and I couldn't find, in fact, in the include files these functions ...
(I am working with the 1.11 version). I am sorry if it is a stupid 
question but I don't know what to do! thanks again!
