Detailed Description

template<typename MatrixType>
class Eigen::SparseView< MatrixType >

Expression of a dense or sparse matrix with zero or too small values removed.

Template Parameters
MatrixTypethe 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.
