2017-06-27 23:57:32 +0100 | asked a question | Vertices of Polytope Hi! I have a list of points that I'm using to construct a convex, finite-sided, compact polytope: I know how to extract from P1 the list of vertices that define it: This returns the following output: But what I'd like to do is have a list of the coordinates of the vertices only: i.e have sage tell me a list of the form [(.5,0), (-.5, 0), (-.5, 1), (.5, -1)], so that I can do some computations about P1 that are dependent on the coordinates of the vertices. Is there a way to do this? Thanks! |
2017-06-12 16:23:22 +0100 | commented question | Recasting Laurent polynomials Also, I have already seen (https://ask.sagemath.org/question/33260/gcd-of-multivariable-polynomials-and-conversion-of-laurent-polynomials-to-ordinary-polynomials/ (https://ask.sagemath.org/question/332...)), but it didn't help me fix the issue at hand. Thanks again! |
2017-06-12 16:23:22 +0100 | asked a question | Recasting Laurent polynomials Hi, I have 2 Laurent polynomials, f and g, and I'm trying to recast them into multivariable polynomials over ZZ (I'm eventually going to take their gcd). However, I'm not able to do so on the Sage Cloud. So far, I've tried the following:
However, this didn't help, because SAGE thinks the type is: so I still can't take the gcd.
Any suggestions would be greatly appreciated!! Thanks so much. |
