Detailed Description

Borrowed third-order TOPP/COPP profile view.

Profile3rdRef mirrors Rust's Topp3ProfileRef: it borrows node-based a(s) = dot{s}^2 and b(s) = ddot{s} arrays plus the effective stationary interval counts at the beginning and end. The referenced arrays are not copied and must outlive the call that consumes this view.

The slice helpers use inclusive station indices, matching IndexInterval: slice(i, j) borrows nodes i..=j and adjusts stationary counts for the local profile.

slice()

Profile3rdRef copp::Profile3rdRef::slice	(	std::size_t	idx_s_start,
		std::size_t	idx_s_final ) const

Borrow a closed station subrange idx_s_start..=idx_s_final.

Returns

A new non-owning profile view whose a/b spans point into the original arrays. Stationary-boundary counts are clipped to the local subrange.

Exceptions

copp::Error

if the interval is empty, out of range, or would be entirely stationary.

segment()

Profile3rdRef copp::Profile3rdRef::segment

(

std::size_t

idx_s

)

const

Borrow one segment as the two-node profile idx_s..=idx_s+1.
