URL: <http://savannah.gnu.org/bugs/?49690> Summary: inv(inf) behaves differently from inf^-1, 1/inf, inf\1 Project: GNU Octave Submitted by: None Submitted on: Thu 24 Nov 2016 08:06:58 AM UTC Category: Octave Function Severity: 3 - Normal Priority: 5 - Normal Item Group: Incorrect Result Status: None Assigned to: None Originator Name: Originator Email: address@hidden Open/Closed: Open Discussion Lock: Any Release: 4.0.3 Operating System: GNU/Linux _______________________________________________________ Details: octave:1> inv(inf) warning: matrix singular to machine precision ans = Inf octave:2> inf^-1 ans = 0 octave:3> inf\1 ans = 0 octave:4> 1/inf ans = 0 I'm not sure whether this is a bug since "inf" is not a finite value, and I'm not sure whether it is required that inv() should behave exactly as ()^-1 . Also, I'm sorry that I have no Octave 4.2.0 installed so I could not help to test this on the new released version. _______________________________________________________ Reply to this item at: <http://savannah.gnu.org/bugs/?49690> _______________________________________________ Message sent via/by Savannah http://savannah.gnu.org/
