Follow-up Comment #7, bug #52904 (project octave):
@Markus: Wow, Matlab's messages don't seem any more useful than Octave's. For
completeness, could you run the original motivating example:
Z = logical (ones (25,25));
h = mesh (Z);
My guess now is that this is an unsupported syntax and this will also produce
an error.
If it does then I think there are two possibilities: 1) increase the the input
validation either in surface.m or within graphics.cc, 2) ignore input
validation, and make sure that a partially complete graphics object can not be
constructed and returned.
As an example of what is wrong,
h = surf ('foobar')
error: set: invalid number of arguments
error: called from
surface>__surface__ at line 189 column 5
surface at line 63 column 19
surf at line 72 column 10
ishghandle (h)
error: 'h' undefined near line 1 column 13
get (gca, 'children')
ans = -18.192
hs = ans
hs = -18.192
get (hs, 'type')
ans = surface
h is not defined, but the current axes does contain a surface object. That is
probably not right, and not what Matlab does. Maybe the whole object creation
needs to be wrapped in an unwind_protect to remove the object if the
constructor fails.
