Detailed Description

template<class L, std::size_t IB, class IA, class JA, class TA>
class boost::numeric::ublas::compressed_matrix_view< L, IB, IA, JA, TA >

Present existing arrays as compressed array based sparse matrix.

This class provides CRS / CCS storage layout.

see also http://www.netlib.org/utk/papers/templates/node90.html 

 \param L layout type, either row_major or column_major
 \param IB index base, use 0 for C indexing and 1 for
 FORTRAN indexing of the internal index arrays. This
 does not affect the operator()(int,int) where the first
 row/column has always index 0.
 \param IA index array type, e.g., int[]
 \param TA value array type, e.g., double[]
