Detailed Description

template<Rank rank>
struct syten::DenseIterRestricted< rank >

Restricted iterator.

Behaves much like DenseIter, but can keep some indices fixed at a specified value.

This is achieved by a third argument fixed_ of the constructor.

Performance is worse than the plain DenseIter when iterating over the whole array, but much better if at least one (non-trivial) dimension is kept fixed.
