template<typename
MatrixType>
class Eigen::SparseView< MatrixType >
Expression of a dense or sparse matrix with zero or too small values removed.
- Template Parameters
-
MatrixType | the type of the object of which we are removing the small entries |
This class represents an expression of a given dense or sparse matrix with entries smaller than reference
* epsilon
are removed. It is the return type of MatrixBase::sparseView() and SparseMatrixBase::pruned() and most of the time this is the only way it is used.
