NCMatrix * NCRingElement -- Product of NCMatrices

Synopsis

Operator: *
Usage:

L = M*f
Inputs:
- M, an instance of the type NCMatrix,
- f, an instance of the type NCRingElement,
Outputs:
- L, an instance of the type NCMatrix,

This command allows for the scalar multiplication of an NCMatrix by an NCRingElement on the right.
