I'm closing this bug as a duplicate of bug #54941, where there has been slightly more discussion and examples shown. Also a workaround shown there is to define the method prototype in the class definition.

Confirmed in the development version of Octave as well.

One notable way this does work is if the class is defined using classdef syntax, and if all the methods are defined in the class body, or at least with prototypes in the class body.  For example

classdef polynomial < handle
    disp (p);
    a = double (p);

If I create the following class (from the documentation)


I am able to use the class as:

>> p = polynomial([-1 0 1])

p = - 1 + X ^ 2

>> display(p)

p = - 1 + X ^ 2

However, if I put this in a +package as follows:

Then the function "display.m" is not resolved.

>> p = polynomial([-1 0 1])

p = <class polynomial>

>> display(p)

p = <class polynomial>

If I insert the display function inside the polynomial.m file it is once more resolved correctly.

So in effect it doesn't register the location of the class correctly.
