Distance between two quintic splines

Description

Calculate the distance between two quintic splines, as measured by the integral of the square of the difference. Also calculates the derivatives of that distance with respect to the spline parameters of the second function.

Usage

distance_spline(
  x0,
  x1,
  y0,
  y1,

  a1,
  y0new,
  y1new,
  s0new,
  s1new,
  a0new,
  a1new
)
