Update of bug #42408 (project octave):
Summary: Incorrect results of isequal() with empty sparse
matrices and alphanumerical value comparision. => Matlab incompatible results
for isequal() with character/double comparisions
_______________________________________________________
Follow-up Comment #3:
I checked in a change that matches the return sizes Matlab uses for uncommon
inputs (like 0x1, 1x0, 1x1 (but empty))
(http://hg.savannah.gnu.org/hgweb/octave/rev/a5286fb173cd). That takes care
of the first problem which is the worst.
The other two comparisons are because Matlab seems to internally promote
characters to a numeric class. Could you try running these experiments?
x = single (83);
y = single (84);
isequal ([x y], 'ST')
x = complex (83, 0)
isequal (x, 'S')
isequal (uint8 (83), 'S')
