No problem. Thanks for the update.

OK, I've applied your patch and made some further changes. I have
generally followed a policy of making objects that are to be returned
by the function be optional arguments, with the correctly sized object
being made by default, thereby sparing the programmer from having to
think about it. Towar
Yes, I was thinking the same thing. I created a new patch and tested the
example.
There is also the issue of the ls-covariance function requiring a raw
pointer to the Jacobin matrix. I just exported the jacobian function in
the attached patch.

Hmm, so it does. I'm wondering if fit-test-delta is always
called with last-step and current-position derived from the
same fit object. In which case, would it make sense
to just have one argument there, the fit object?
E.g. (fit-test-delta fit 1.0d-4 1.0d-4)
What do you think?

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
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 origin
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
