[sage-support] how to construct a splitting field of a polynomial

I'm trying to work with some roots of a rational polynomial, but I can't seem to get it to work. One example is z^3 + 1/3 I seem to be able to get the splitting field from: R.=PolynomialRing(QQ) K.=NumberField([z^3 + 1/3]) R.=PolynomialRing(K) print (z^3 + 1/3).factor() L.=NumberField([z^2 + a

Re: [sage-support] Re: semidefinite programming using csdp -- python import errors

I've also been using CSDP from Sage lately. I am calling the stand-alone program, rather than using the Python interface (which isn't a very good solution). I was wondering whether using pycsdp is the right way to go though. Wouldn't it be best to write a small Cython wrapper for the C library? (I

Re: [sage-support] Re: Exporting data from sage notebook

Thanks for the answer Dima, I tried this: - import csv o=open('test.csv','wb') output=csv.writer(o) data=[[1,2],[3,4],[5,6]] for r in data: output.writerow(r) o.close() I'm afraid that that doesn't work either (still output an empty csv file). Note that I have never had to use

[sage-support] Exporting data from sage notebook

Hi all, I've had trouble with this for a while. If I write the following in to a notebook cell: -- import csv output=csv.writer(open('test.csv','wb')) data=[[1,2],[3,4],[5,6]] for r in data: output.writerow(r) - and evaluate, a hyperlink appears entitled 'test.csv', if I open t
