Follow-up Comment #1:
I think I see the issue. Octave recently changed so that you could create a
sparse matrix and then fill it without reallocating memory at each assignment,
and as a result removed the assumption that nnz = nzmax in octave. Changes
were made in a number of places to handle this change, but the matlab file
format in this case was unclear from the documentation and I made a guess on
how matlab treated the case of nnz not equaling nzmax (as I no longer have
access to matlab) it appears that this guess was wrong.
The simpler example
a = spalloc (2,2,4); s(1,1) = 1; s(2,2) = 2;
b = 1;
save -v6 a.mat a b
demonstrates this error more easily.. To make my life easier could you run
the above in matlab and upload the saved file so I can compare what matlab
does in this case.
