I'm doing numerical minimization on it right now and the only reason I
want/need it to be a sage function is so I can .subs() real values for
my parameters. To get around that, I'm just going to use global
variables for my parameters. It's kind of ugly, but it will work. It
would be nice
M.units() will give a set of units which are a Z-basis for the units
modulo roots of unity. There is no canonical basis, so there's no
reason why (even if the unit ranks are the same) you should get the
same generators.
For more functionality with units construct U=X.unit_group() and look
at

I would recommend looking at how Mathematica handles this sort of
thing. One of the things I miss is its ability to selectively treat
different variables as either part of a coefficient ring or as
multivariate polynomials. For example:

For a field extension over Q of 2 values, for example M=QQ(i, sqrt
(2)), it is possible to find an absolute field X by the following
L.b=NumberField(x^2-2)
R.t=L[]
M.c=L.extension(t^2+1)
(this gets M)
X.d=M.absolute_field()
I guess I was trying to say that it would be nice if that could be
done more easily, like if one could do
sage: var('x,y,z')
sage: fs = [x^2*y - y, sin(z)*x*y^2 - y*sin(z)]
sage: SR.groebner_basis(fs, [x,y])

Robert,
Should those double complex declarations give any speedup?
Are they declaring the numpy complex type or something else?
Slightly unrelated, how are self.something variables handled? It seems
like you can't cdef them, so are they then always going to be slow? If
you cdef a variable and

Yes, lots (compared to using Python complex objects). The are complex
analogues of int, double, float, etc.

Robert, Thanks for the feedback. I don't want to wait for 4.1.1 so I
will attempt to follow the Sage Days 16 How to get started with
developing Sage to apply the patches. At first look this does not

Is there any prediction for when numpy complex types will work?
