Detailed Description

template<typename number>
class ChunkSparseMatrixIterators::Accessor< number, true >

Accessor class for constant matrices, used in the const_iterators. This class builds on the accessor classes used for sparsity patterns to loop over all nonzero entries, and only adds the accessor functions to gain access to the actual value stored at a certain location.
