Function resid::spline::interpolate

pub fn interpolate(points: &[Point], plotter: &mut PointPlotter, res: f64)

Evaluation of complete interpolating function. Note that since each curve segment is controlled by four points, the end points will not be interpolated. If extra control points are not desirable, the end points can simply be repeated to ensure interpolation. Note also that points of non-differentiability and discontinuity can be introduced by repeating points.
