NCMatrix _ ZZ -- Induced map in homogeneous degree n

Synopsis

Operator: _
Usage:

m = M_n
Inputs:
- M, an instance of the type NCMatrix,
- n, an integer,
Outputs:
- m, a matrix,

Description

If we regard M as defining a map of graded right free modules, then M_n returns the induced map of underlying R-modules in degree n, where R is the coefficient ring of ring M.
