[Octave-bug-tracker] [bug #59477] __ode15__.cc does not consider the number of arguments in the event function

[Hg200]

Follow-up Comment #6, bug #59477 (project octave):

I cleaned the code a bit and attached the patch. The idea is that when calling
the function "__ode15__()" in ode15i.m and ode15s.m, an additional parameter
is passed that controls the number of arguments in the ode event callback.
Thus __ode15__ can provide the required number of arguments for ode15s and
ode15i functions at line 775.

The question about runtime is tricky. I tried again a bit harder: Rebooted, no
X-server and ran Octave + examples below from bash. This time i got 6% for
ode15s and 0.5% for ode15i (wrapper slower than C-solution). That confirms the
measurement below. But if I choose another ode problem that requires much more
runtime, then both solutions have nearly same runtime. So it seems also to
depend on the use case.
