The quotient of `ZZ[x]` by the ideal `(x, 2)`
works fine using a multivariate polynomial ring:
```
sage: R. = PolynomialRing(ZZ, 1)
sage: I = R.ideal([x, 2])
sage: I
Ideal (x, 2) of Multivariate Po…

Hi,
Thanks for the great library!
I'm wondering how I can operate on matrices or vectors of polynomials. I have tried this:
`@polyvar rot_mat_flat_var_original[1:num_internal_bodies, 6]
`

We try to abstract away the concept of active ring in Singular, by either adding the ring to objects which are ring dependant (such as polys), or else adding the ring as an explicit parameter to comm…

A `noexcept` function should not call any function that could raise an exception. This includes any python function. As you see below, there are 572 cases of this. PR #37792 fixes one :f…
