Re: [Help-gsl] fitting - nonconstant point distance

hello, I am sorry for ambiguousity, I have been working on nonlinear least squares fitting (chapter 37). I have had deeper look in my english dictionary :) and I think I got the idea of the solver (actually it solves also my problem). When I fill f vector in function which is supposed to compute v

hello, I would like to know if it is possible to fit points, which have nonconstant distance (for example I know values in time 0,1,3,5,8,10,11). Is it possible to set this somewhere? Or do I have to "linearize" it first (aproximate values which I dont know to make the distances constant)? bes
