2016年3月20日 · What are the advantages and disadvantages of piecewise linear interpolation, cubic interpolation, and cubic spline interpolation? I know that piecewise linear interpolation is not smooth and may not be accurate for nonlinear functions. The other two are smooth. But I think my understanding is a little superficial.

2014年11月5日 · The hollow (white points) indicate the places where the quadratic segments join together, sometimes called knot points. The spline is a little strange because the knot points do not coincide with the interpolated points, as they would on a cubic spline. This spline has a knot sequence $(0,0,0, 0.3, 0.7, 1,1,1)$.

2019年4月14日 · For spline interpolation, it looks the degree 3 cubic spline is accepted as the better way and in my understanding it requires 1st and 2nd derivatives at the joints to be the same. Question It looks to me the second order spline can provide smooth continuity at the joints, so it can satisfy the same value and smooth continuity at the joints.

Interpolate a cubic spline between the three points $(0, 1), (2, 2) \text{ and } (4, 0).$ I'm trying to understand how to interpolate a given set of points using cubic splines with the help of this solved example .

2021年2月10日 · So far I have studied cubic Hermite interpolation has a less computational cost and does not have issues like undershoot and overshoot as compared to cubic spline interpolation. My question is what are the advantages of cubic spline interpolation over cubic Hermite interpolation?

Spline interpolation - why cube with 2nd derivative? 1 Does not-a-knot cubic spline interpolation always have a tridiagonal system of equations when solving for the second derivatives?

2017年6月9日 · I want to figure out how to calculate a cubic spline using 3d points. The wiki page shows a good example for 2d points but I just cannot find any resources that would let me do it with a 3d point aka P(x,y,z). I don't understand how to add a z into the equations given and I'm not great at math so I need a clear explanation of how to do this.
