[Octave-bug-tracker] [bug #51965] ode functions decic, ode15i, and ode15s are not mentioned in NEWS or manual

[Colin Macdonald]

Follow-up Comment #5, bug #51965 (project octave):

1.  Runge–Kutta is common usage in numerical analysis.  I looked for a
reference: the [wikipedia page](https://en.wikipedia.org/wiki/Dash#En_dash)
talks about "Bose&ndeshEinstein"

> ...while others consider an en dash appropriate in instances
> such as this[18][19][20] to represent the parallel
> relationship, as in the McCain–Feingold bill or
> Bose–Einstein statistics. 

I also searched "endash names in mathematics" but haven't really found an
authoritative source yet...


2.  y' = 0 = f(t,y,y') is wrong.  The previous docs were wrong.  The
fully-implicit case is 0 = f(t,y,y'), that is where y' is described implicitly
by f = 0.  This is contrast with the usual y' = f(t, y)
