[Octave-bug-tracker] [bug #59617] [octave forge] (interval) Failure in building the documentation against Octave 6.1

[Rafael Laboissiere]

Follow-up Comment #1, bug #59617 (project octave):

I narrowed down the problem to the following example:

This works with Octave 5:


$ octave-cli --version | head -n 1
GNU Octave, version 5.2.0
$ echo 'pkg load interval; fsolve (@sin, infsup (-1, 1))' | octave-cli -q
ans = [-0.0078125, +0.0078125]


but fails with Octave 6:


$ octave-cli --version | head -n 1
GNU Octave, version 6.1.0
$ echo 'pkg load interval; fsolve (@sin, infsup (-1, 1))' | octave-cli -q
error: Invalid call to fsolve.  Correct usage is:

 -- fsolve (FCN, X0)
 -- fsolve (FCN, X0, OPTIONS)
 -- [X, FVAL, INFO, OUTPUT, FJAC] = fsolve (...)
[…]


Is this a problem in Octave 6 (overloaded function not being recognized) or a
problem in the interval package?
