I can't trigger that bug on OS X 10.3.6 with octave 2.1.64, see below.
Problem with Mandrake?
/Per
> M
M =
1 + 1i 1 + 1i
1 + 1i 1 + 1i
> sqrt(M/0)
warning: division by zero
ans =
NaN + NaNi NaN + NaNi
NaN + NaNi NaN + NaNi

Hi,
I'm currently use an octave version 2.1.57 on a Mac OSX 10.3.6 and a
2.1.64 compiled from sources on a mandrake 10.1.
I've a couple of functions which return a matrix M of complex numbers
with NaN in it. Display the content of M give NaN + (or -) NaNi in
case of NaN. I need to calculate the square root of M. On 2.1.57, sqrt
function works perfectly and returns NaN + (or -) NaNi in case of NaN.
But on 2.1.64 octave hangs without error or returning to prompt.
Any idea ?
Samir.
