tscMatrix-class {Matrix} | R Documentation |
The sscMatrix
class is a class of triangular, sparse
matrices in the compressed, column-oriented format. In this
implementation the non-zero elements in the columns are sorted into
increasing row order.
Objects can be created by calls of the form new("tscMatrix", ...)
.
