[Octave-bug-tracker] [bug #43925] isscalar behaves incorrectly for some user-defined classes

[Julien Bect]

Follow-up Comment #9, bug #43925 (project octave):

Ooops, there are so many typos in my previous message that if find it hard to
read... I meant:

For matlab compatibility, ismatrix must return true for sizes such as 0x1 or
1x0. The rule is that ismatrix returns true if the size is [m n] for
non-negative integers m and n.

I have just tested without the sz>=0 tests, and all the unit tests still pass.
 I will prepare a modified patch later.

In the meantime, I am currently which xtest statements in
test/classes/classes.tst can now be converted to test.

I have also found out that columns() and rows() suffer from exactly the same
problem. I will extend the patch to deal with them as well.
