[sage-support] Can sage's palp decompress these polytopes?

Kreuzer has a list of five-dimensional reflexive polytopes at this link: http://quark.itp.tuwien.ac.at/~kreuzer/d5/ I want to read these compressed files. Is this possible in sage? -- You received this message because you are subscribed to the Google Groups "sage-support" group. To unsubscribe

[sage-support] v3 (3d vector gives an error)

The third vector is an error, is it a bug ? v1=vector([3,4,-6]) v2=vector([-4,3,10]) v3=v1.dot_product(v2) p1=v1.plot(color='red') p2=v2.plot(color='green') p3=v3.plot() --- AttributeError Traceba

r is resistance it 's a RC circuit. I got this from arachnoid : http://arachnoid.com/sage/differential1.html But while trying to make it work I probably mess it ! sorry ! Nothing to do with r ... I will remake it in a proper way jupyter notebook, sorry for the disturbance :) Henri Le 05
