Constructor & Destructor Documentation

template<class T, class S> crs_matrix< T, S >::crs_matrix (  const vector< T > &  _cnt, const vector< T > &  _col, const vector< S > &  _val )  [inline]

The constructor takes the count, column and matrix value vectors of the compressed row matrix storage format. Parameters: _cnt  Input: Vector of column index counts. _col  Input: Vector of column indices. _val  Input: Vector of matrix values.
