dsCMatrix-class: Symmetric, compressed, sparse column matrices

Description

The dsCMatrix class is a class of symmetric, sparse matrices in the compressed, column-oriented format. In this implementation the non-zero elements in the columns are sorted into increasing row order. The dsTMatrix class is a class of symmetric, sparse matrices in triplet format.

Objects from the Class

Objects can be created by calls of the form new("dsCMatrix", ...) or new("dsTMatrix", ...)
