That is unfortunate. Clearly, the author of the library explicitly does not
want his code used in octave.

That's an interesting approach. I really hate it though, because it ends up
doing exactly the same thing (enabling use of non-free software in octave)
but now also benefits the Mathworks. Well, if someone want's to do this
maybe the MEX interface here can help:

I have no idea if it works in octave or if the functionality there is
equivalent.

Also unfortunate. Next of kin are probably irrelevant, though, as it seems
to have been written while the author was an employee of Philips and
probably represents work-for-hire.

Maybe confusing copyright and patent durations? In the Netherlands,
copyright extends 70 years after death (
