Matrix-methods: S4 methods for products of matrix objects

Description

Several methods for products of matrix objects. Here a matrix object can be an ordinary (dense) matrix or a (sparse) Matrix of class ddiMatrix-class, tabMatrix, dgCMatrix-class, or dsCMatrix-class. The return types are restricted to matrix or numeric in case of dense objects, and dgCMatrix, dsCMatrix, ddiMatrix or tabMatrix in case of sparse objects.

Arguments

x

a matrix object.

y

a matrix object.

Value

A matrix object. In case one of the arguments is a regular (dense) matrix the result is a matrix as well.
