Detailed Description

template<typename number>
class SparseMatrixIterators::Accessor< number, false >

Accessor class for non-constant matrices, used in the 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.
