Internally, no. For you, yes, they are; you shouldn't normally care
about whatever Octave does to choose the best internal representation
of each.

Octave in general has pretty weak type checking , but there are
various isfoo functions you can use to check for type foo.

Just return matrices from your functions. Octave also supports
returning simultaneous multiple return values from a function.
