Magma object from magma.eval()?
How can I get a Magma object to use inside of Sage from something created in Magma through magma.eval()? Is this possible?
Suppose you created a polynomial in Magma with the following command:
sage: magma.eval('R<x> := PolynomialRing(RationalField()); f := (x-17/2)^3;')
Then, you can get a Sage version of that object like this:
magma('f') part creates an object (
MagmaElement) in Sage which is basically a pointer to the variable
f in the Magma session. (You can actually use this perform calls on this objects which will translate to Magma commands. For example,
magma('f').Factorization() is basically same as doing
magma.eval('result := Factorization(f);') and returning
sage() method will convert a
MagmaElement to the corresponding Sage object if possible.
