Re: [Bug-gsl] non-linear LS fit example in documentation: bug?

Brian,

OK. That makes sense. Thanks for looking into that. Looks like using the 
"break" will save a few iterations.

I guess that having the solver return a "continue" and having that cause 
the program to exit the iteration loop was making me nervous.
