Eigen::Ref
template<typename SparseMatrixType, int Options>
class Eigen::Ref< SparseMatrixType, Options >
A sparse matrix expression referencing an existing sparse expression.
- Template Parameters
-
SparseMatrixType the equivalent sparse matrix type of the referenced data, it must be a template instance of class SparseMatrix. Options specifies whether the a standard compressed format is required OptionsisStandardCompressedFormat, or0. The default is0.
