Cubic spline interpolation rechner
WebThe fundamental idea behind cubic spline interpolation is based on the engineer ’s tool used to draw smooth curves through a number of points . This spline consists of weights attached to a flat surface at the points to be connected . A flexible strip is then bent across each of these weights ,resulting in a pleasingly smooth curve .
