Follow-up Comment #5, bug #49690 (project octave):

The trouble was actually buried in liboctave where we are changing the matrix
to all Inf if the reciprical condition number is 0.

I've fixed things for the ordinary cases.  But what does Matlab do for


x = complex (1, inf);
1 / x


When I have the answer for that I can make inverse(x) and 1 / x yield the same
result across all inputs.
