Detailed Description

template<typename SparseMatrixType, int Options>
class Eigen::Ref< SparseMatrixType, Options >

A sparse matrix expression referencing an existing sparse expression.

Template Parameters
SparseMatrixTypethe equivalent sparse matrix type of the referenced data, it must be a template instance of class SparseMatrix.
Optionsspecifies whether the a standard compressed format is required Options is StandardCompressedFormat, or 0. The default is 0.
