[Bug-gsl] [bug #30947] Please, include fixed step size control object for ode suite

[Tuomo Keskitalo]

Follow-up Comment #1, bug #30947 (project gsl):

Hi,

one important reason for the evolve level functions is to allow for variable
step size. If you really require a fixed step size for the stepper level, then
you can use the for loop around step_apply function shown in the manual. 

Also, I'm afraid that using your cfxd may not guarantee the use of a fixed
step size; also evolve_apply can change the step length, so you might have to
have a function something like "evolve_apply_fixed_step_size" to do the job.

BR,
Tuomo
