Dear sage-devel, I have two things I just want confirmation of before I file tickets - such as an alternate way/workaround to do these things which I have missed. Thanks for any replies.
- kcrisman 1. There is no way to get a symbolic interpolated polynomial de novo without going through polynomial rings, e.g. all these steps: pts = [(1,2),(2,3),(3,2),(4,3),(5,2),(6,3)] R.<x>=QQ[] f = R.lagrange_polynomial(pts) SR(f) 2. If one has a non-symbolic polynomial currently, it won't plot with the new plotting syntax. plot(f,0,5) # works, old-school Sage plot(f,(x,0,5)) # doesn't work, new-school Sage plot(f,x,0,5) # doesn't work, though sort of makes sense it shouldn't since x isn't a symbolic variable now... ? If there was a direct interpolated polynomial for SR I wouldn't have noticed the second one. -- To post to this group, send an email to [email protected] To unsubscribe from this group, send an email to [email protected] For more options, visit this group at http://groups.google.com/group/sage-devel URL: http://www.sagemath.org
