pub fn elevated_breaks(curve: &Elevated3, k: usize) -> Vec<f64>Expand description
Where an elevated curve may fail to be C^k (k >= 1), ascending: a
chain plan’s joins and every seam of the elevation law (the grade may
jump there), and for k >= 2 the curvature seams of an intrinsic plan
or of a chain’s intrinsic pieces.
