[Octave-bug-tracker] [bug #56232] Octave crash when inverting an empty sparse matrix.

[John W. Eaton]

Follow-up Comment #39, bug #56232 (project octave):

What happens if, instead of the divide by zero warnings, you create a +/-Inf
or NaN element in the output at the location in the output array where the
divide by zero would have occurred?  +/-Inf if the numerator is non-zero and
NaN if it is 0 (not present).  I think this change will require some care,
because the zero in the denominator could (or would?) be a value not stored in
the sparse array.  I've looked at tinverse, but I don't know immediately see
how to modify it to do what I'm suggesting.
