Hi people, how do I set the fsolver type in gsl? When I use fdfsolver the case is clear it goes like this: constgsl_multifit_fdfsolver_type *T;gsl_multifit_fdfsolver *s;T =gsl_multifit_fdfsolver_lmsder;s =gsl_multifit_fdfsolver_alloc(T,n,p);gsl_multifit_fdfsolver_set(s,&f,&x.vector); But how am I supposed to do it for a fsolver: constgsl_multifit_fsolver_type *T;gsl_multifit_fsolver *s;T=????? What I want to do is the following. I have a polynom which I want to fit to some 3D data. The fsolver should fit the coefficients of the polynom. I want to use fsolver because inside the fitting function I need to set all the coefficients to be positive. Thanks for your help.
