2017-09-01 Thread Carlo Verschoor
Hello, I had this problem with plotting fans in Sage 8.0 which still works in Sage 7.6. The problem breaks down to the following piece of code: cones = [Cone([(0,1),(1,0)]),Cone([(-2,-1),(-1,-3)]),Cone([(0,1),(-2,-1)]), Cone([(-1,-3),(1,0)])] F = Fan(cones) F.plot() I get an "unable to simplif
