描述----------Description----------

The dgCMatrix class is a class of sparse numeric matrices in the compressed, sparse, column-oriented format.  In this implementation the non-zero elements in the columns are sorted into increasing row order.  dgCMatrix is the “standard” class for sparse numeric matrices in the Matrix package.
dgCMatrix类是一类稀疏的数字矩阵压缩，稀疏，面向列的格式。在此实现在列的非零元素增加行顺序排序。 dgCMatrix是Matrix包类稀疏的数字矩阵“标准”。


类的对象----------Objects from the Class----------

Objects can be created by calls of the form new("dgCMatrix", ...) or often more easily via Matrix(*, sparse = TRUE).
对象可以创建的形式电话new("dgCMatrix", ...)或往往更容易通过Matrix(*, sparse = TRUE)。


插槽----------Slots----------




x: Object of class "numeric" - the non-zero
x类"numeric"对象 - 非零




... all other slots are inherited from the superclass "CsparseMatrix".
...其他所有插槽都继承自父类的"CsparseMatrix"。
