matrix.csr-class: Class "matrix.csr"
Description
A new class for sparse matrices stored in compressed sparse row formatObjects from the Class
Objects can be created by calls of the form new("matrix.csr", ...).
and coerced from various other formats. Coercion of integer scalars
and vectors into identity matrices and diagonal matrices respectively
is accomplished by as(x,"matrix.diag.csr") which generates an
object that has all the rights and responsibilties of the matrix.csr class.
The default matrix.csr object is a scalar (1 by 1) matrix with element 0.
