extmat-class (Package: svd) : Class code{"extmat"

'extmat' is a convenient wrapper which allows one provide just the routines which will multiply with matrix and the transposed one (e.g. if the matrix is sparse or structured) and allow to use the SVD routines of the package. This S4 wrapper allows the use of usual matrix operations on such objects.
