Dear SAGE community, I would like to do some symbolic computation using SAGE, namely, to compute the extended GCD of two polynomials, one of them having symbolic coefficients.
Here is a short example: sage: R.<a,b>=PolynomialRing(RationalField(),2); sage: S.<x>=PolynomialRing(R); sage: xgcd(x^2,a+x*b) As an answer, I would expect: (b^2/a^2, 1, -x/a+b/a^2) However, this raises the error: <type 'exceptions.TypeError'>: cannot coerce nonconstant polynomial Am I missing a way of actually doing the computation in SAGE or is this just not implemented yet? Thanks for your help, --Gaetan Bisson --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to [email protected] To unsubscribe from this group, send email to [EMAIL PROTECTED] For more options, visit this group at http://groups.google.com/group/sage-support URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
