basis({...},Module) -- basis of the part of a module of a certain degree

basis({...},Module) -- basis of the part of a module of a certain degree

Synopsis:

Usage: f = basis(i,M)

Function: basis

Input:

i, an instance of class List: the degree of the desired part of the module

M, an instance of class Module: a module

Output:

f, an instance of class Matrix: a map from a free module to M which sends the basis elements to a basis, over the ground field, of the degree i part of M.

The degree i is a multi-degree, represented as a list of integers. If the number of degrees is just 1, then i may be provided as an integer.
