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

[Marco Caliari]

Follow-up Comment #50, bug #56232 (project octave):

@Rik:

1) I see that in the full case, octave already returns a matrix full of Inf
values. Preserving the sparsity pattern in the sparse case is the most similar
thing I can imagine (although it does not work in the null case, I know).
Anyway, no real high value.

2) If I had to check whether the inversion of a matrix was successful, as
first option I would test the result with isinf, not isnan. But if we decide
for NaN, we should change the behavior in the full case, too.

For things like these, shouldn't we use the developers mailing list?
