[Help-gsl] Adding additional argument in the functions defined in gsl_siman.h

[Brijesh Upadhaya]

Hi!

I am currently using Simulated Annealing for my work. The routines work
really nice, however, I had to add few more arguments to some of the
functions. I did this for passing the arrays read from the data file and
some additional model parameters. The main reason behind additional changes
were to calculate mean absolute error (Cost function) with the simulated
and measured data.

I found out that the following changes to the routines described in
gsl_siman.h would be required for the one who need to pass the parameters
and measurement data. I have added the work_space pointer to void:

typedef double (*gsl_siman_Efunc_t) (void *x, *void *work_space*);
>
> typedef void (*gsl_siman_step_t) (const gsl_rng * r, void *xp, double
> step_size, *void *work_space*);

It would be nice if the above changes would be made in the future release.

Kind regards,
