Expand description
Implements the knot vector defining the spline basis functions.
The knot vector parametrizing the k-th degree curve is composed of n+p+2 - 2k scalar values
in ascending order, called ‘knots’.
The head and tail contains of p-k+1 knots of value 0 and 1, respectively.
This leaves n-p internal knots in the center.
The interval from index i = p-k,..., n+1-k is called ‘domain’.
Different knot vector generation methods are available.
