Detailed Description

template<class DataType, class Arg1Type, class Arg2Type = void, typename SizeType = typename ViewTraits<DataType*, Arg1Type, Arg2Type, void >::size_type>
class Kokkos::CrsArray< DataType, Arg1Type, Arg2Type, SizeType >

Compressed row storage array.

Template Parameters

DataType	The type of stored entries. If a CrsArray is used as the graph of a sparse matrix, then this is usually an integer type, the type of the column indices in the sparse matrix.
Arg1Type	The second template parameter, corresponding either to the Space type (if there are no more template parameters) or to the Layout type (if there is at least one more template parameter).
Arg2Type	The third template parameter, which if provided corresponds to the Space type.
SizeType	The type of row offsets. Usually the default parameter suffices. However, setting a nondefault value is necessary in some cases, for example, if you want to have a sparse matrices with dimensions (and therefore column indices) that fit in int, but want to store more than INT_MAX entries in the sparse matrix.

A row has a range of entries:

• row_map[i0] <= entry < row_map[i0+1]
• 0 <= i1 < row_map[i0+1] - row_map[i0]
• entries( entry , i2 , i3 , ... );
• entries( row_map[i0] + i1 , i2 , i3 , ... );
