[Octave-bug-tracker] [bug #36603] sparse matrices with no nonzero elements cannot be loaded in Matlab

[Jordi Gutiérrez Hermoso]

Follow-up Comment #2, bug #36603 (project octave):

I just spent some time looking byte-for-byte at the resulting mat files, and
I'm quite stumped. As far as I can tell, Octave obeys the published spec for
mat files.

Could you please show me the following mat files? I'll try to reverse-engineer
the format that Matlab expects:


o = sparse(108,0);
save -v7 o.mat o;
x = sparse(108,108);
save -v7 x.mat x;
s = x;
s(500) = 42;
s(1000) = inf;
save -v7 s.mat s;


Then send me s.mat, o.mat, and x.mat.
