Follow-up Comment #1, bug #37321 (project octave):

This looks like two bugs in one.

First, for the example you give, __isequal__ is computing


all (sparse (0, 1))


and getting the sparse(1,1) result.  But


all (zeros (0, 1))


produces logical(1).  So shouldn't the sparse version produce logical (sparse
(1))?  Then the second bug is that isequal should be returning a full matrix
in this case instead of sparse.
