2.1 ideal

Under an ideal PLURAL understand a left ideal. Ideals are represented as lists of polynomials which are interpreted as left generators of the ideal. For the operations with two-sided ideals see twostd.

Like polynomials ideals can only be defined or accessed with respect to a basering.

Note: size counts only the non-zero generators of an ideal whereas ncols counts all generators.
