Follow-up Comment #2, bug #49129 (project octave):
The legendre function does *not* compute the Legendre poynomials, but the so
called "associated Legendre polynomials" (called "associated Legendre
functions" in Matlab). They are not polynomials for m odd. All of them are
well defined in [-1,1]. For me, the only possible change could be in the
documentation, from "Legendre function" to "associated Legendre polynomial"
(wikipedia) or "associated Legendre function" (matlab).
