[Octave-bug-tracker] [bug #36732] interp1 does not check input for monotonicity

[Michael Godfrey]

Follow-up Comment #36, bug #36732 (project octave):

About non-distinct points, I am assuming that the
Manual is correct. It says in Section 29.1:

Duplicate points in x specify a discontinuous interpolant. There should be at
most
2 consecutive points with the same value. The discontinuous interpolant is
rightcontinuous
if x is increasing, left-continuous if it is decreasing. Discontinuities are
(currently) only allowed for "nearest" and "linear" methods; in all other
cases, x
must be strictly monotonic.

My current patch is attached.
