One-dimensional minimization

[Nicolas Bouche]

Hi 
i am trying to perform a multilinear fit such as,

\chi^2 = (y - X c)^T W (y - X c)

 with W non-diagonal! So gsl_multifit_wlinear  won't do it.

Is there  a routine in GSL to do this?? I couldn't find anything more in
the manual.

Thanks.

Nicolas
