operations_research::glop::CompactSparseMatrixView Class Reference

Detailed Description

A matrix view of the basis columns of a CompactSparseMatrix, with basis specified as a RowToColMapping. This class does not take ownership of the underlying matrix or basis, and thus they must outlive this class (and keep the same address in memory).
