polyMatrix (version 0.3.1)

polyMconvert: Conversion between the pairs of the four polyMatrix subclasses

Description

The polyMatrix package has 4 different but equivalent methods to store the polynomial matrices.

This function provides a conversion between the 4 methods. In the background operates one of the existing 12 subrutines, corresponding to the sub-class of the given input object and the required sub-class of the output object.

Usage

polyMconvert(pm, newclass)

Arguments

pm

an arbitrary polyMatrix class object

newclass

a class identifier character string, one of the following: \ "polyMarray", "polyMbroad", "polyMcells" or "polyMdlist"

Value

A polyMatrix class object, equivalent with the pM input object, but stored in the new, given format by the newclass parameter.
