CGAL::ch_ns_point
Definition
The function ch_ns_point finds the points of a given set
of input points with minimal and maximal x coordinates.
#include <CGAL/ch_selected_extreme_points_2.h>

ch_ns_point ( |
ForwardIterator first,
ForwardIterator beyond,
ForwardIterator& n,
ForwardIterator& s,
Traits ch_traits = Default_traits) |
|
| |
traverses the range [first,beyond).
After execution, the value of
n is an iterator in the range such that *n ≥ yx
*it for all iterators it in the range. Similarly, for
s the inequality *s ≤ yx *it
holds for all iterators in the range.

The default traits class Default_traits is the kernel in which the
type ForwardIterator::value_type is defined.
Requirements
Traits defines the type Traits::Less_yx_2 as specified in
the concept ConvexHullTraits_2 and the corresponding member
function that returns an instance of this type.
