I get the following:
a = FFT(4)
a[1] = 2
a.forward_transform()
Everything works fine up to here. Then, when I do this:
a.backward_transform()
a
I get:
NameError: name 'a' is not defined
Any ideas?

Hi Nathann,
does your code provide for returning infeasibility certificates?
in case of CPLEX Python interface, it's here:
.solution.advanced.dual_farkas()
This is something I need for our research on quantum codes; I have an

amount of smallish LPs, most of them infeasible, and have to

I had forgotten to type "hg add coin_backend* cplex_backend*"
And I of course deleted all the files in the meantime to compile
alpha2, thinking they were in the patch.
I'm in for another try.

Hi sage-devel team,
I have a question concerning the definition of new rings in SAGE.
I would like to generate matrices whose elements are finite formal
sums of words (i.e. linear combinations with integer coeffs of
elements of a free monoid over some finite alphabet).
I was able to get this far

Hi!
My colleague Robert Müller pointed me to the fact that free algebras
in Sage seem to be highly inefficient:
sage: R. = FreeAlgebra(GF(3),3)
sage: f = a^2+b
sage: timeit('g=f^12')
5 loops, best of 3: 1.14 s per loop
GAP does much better:
sage: RG = gap.FreeAlgebra(GF(3),'["a","b","c"]')

I recently updated to sage-4.5.3, binary version, and did a reinstall
and update of R from source.
