[Octave-bug-tracker] [bug #62405] Out of Bound(OOB) on subsindex()

[Glite]

Follow-up Comment #4, bug #62405 (project octave):

I know your input_container(b) means method call. But Octave will interpret
input_container(b) or input_container.b as a indexing to object. 
To call a method in @+ClassName class, I have to write b(input_container).
So maybe this is the real bug?

subsindex is the overloading method that allows the conversion of this class
object to a valid indexing vector.

indexing vector (to be able to index *into* something else). And that seems to
be what is happening (and working ass expected) in your examples.

object with an already existing indexing vector. Is that correct? In that
case, you might want to overload `subsref`:

way round).
