From help-octave-request at bevo dot che dot wisc dot edu Wed Jan 10 06:09:11 2001 Subject: det : singular matrix warning From: Rolf Fabian To: "'help-octave UWISC'" Date: Wed, 10 Jan 2001 13:05:44 +0100 Hi, Currently, I'm frequently using determinants. The following feature is annoying: det with a singular input matrix prints a warning to the screen terminal If det is called in an e.g. iterative program, a lot of such warnings may be displayed. :)det(reshape(1:9,3,3)) warning: det: matrix singular to machine precision, rcond = 0 ans = 0 How to switch-off such warnings ? I didn't find any hint in the manuals. BTW, why is such a warning displayed at all ? To me, it doesn't make any sense because if det(A) returned zero, I'll know that A is singular. What's the reason to warn me in addition? Bye Rolf ------------------------------------------------------------- Octave is freely available under the terms of the GNU GPL.
