Matrix-methods | R Documentation |
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.

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