[Octave-bug-tracker] [bug #46946] isosurface throws errors where Matlab does not

[Philip Nienhuis]

Follow-up Comment #21, bug #46946 (project octave):

Yeah I saw that too, but too late :-)

I was misled by the fact that after a few isosurface manipulations the test
did work.
But now I realize that happens because then  __calc_isovalue_from_data__  has
been called from isosurface and is already in the symbol table. 
Normally, funcs in private/ subdirs can't be called directly (they aren't in
the path), but once called from the parent subdir and parsed they do have a
symbol table slot. Once the symbol table has a specific entry, that entry
doesn't need to be searched on disk anymore. I have no idea about scope etc.
but that must be the way it works.

I'd rather leave the test in. Someday, somehow we'll have a fix for testing
private and nested funcs and subfuncs.

BTW I like the fact that isosurface has been improved quite a bit. The results
look very nice. Thank you very much for that!
