Kernel::Linear_rank_d

A model for this must provide:

template <class ForwardIterator>
int fo ( ForwardIterator first, ForwardIterator last)
computes the linear rank of the vectors in A = tuple [first,last).
Precondition:
Precondition: A contains vectors of the same dimension d.
Requirement: The value type of ForwardIterator is Kernel::Vector_d.
