[Gsll-devel] Patch that exports symbols required to use non-linear fitting outside the gsl package
Hi,
I think some additional exports are required in order to make use of the non-linear least-squares fitting outside of the gsl package. Attached is a patch that achieves this.
Cheers,
Russell
Russell,
Can you give an example showing why this function is needed? If I understand correctly, #'solution gives an marray which can be used like any other marray. As a general practice I don't define functions returning raw pointers unless the exclusive use of the returned value from the original function use is to pass to a GSL function that must take a raw pointer, and that is very rare.

Hi Liam,
The example included at the bottom of gsll/solve-minimize-fit/nonlinear-least-squares.lisp, line 373 (fit-test-delta (last-step fit) (mpointer (solution fit)) 1.0d-4 1.0d-4)) uses (mpointer (solution fit)). Because mpointer isn't exported, I thought I would create a specific function like last-step and jacobian that return raw pointers. I don't really have a good working knowledge of the internals of gsll so this may be a naive fix.
Cheers,
Russell
