Which of the following is correct for spline in interpolation?

The correct answer is (C). In cubic spline interpolation, the first and the second derivatives of the splines are continuous at the interior data points. In quadratic spline interpolation, only the first derivatives of the splines are continuous at the interior data points.

Why is cubic spline interpolation best?

Cubic spline is used as the method of interpolation because of the advantages it provides in terms of simplicity of calculation, numerical stability and smoothness of the interpolated curve.

Which interpolation method is best?

Radial Basis Function interpolation is a diverse group of data interpolation methods. In terms of the ability to fit your data and produce a smooth surface, the Multiquadric method is considered by many to be the best.

Can splines be used for interpolation?

The Spline tool uses an interpolation method that estimates values using a mathematical function that minimizes overall surface curvature, resulting in a smooth surface that passes exactly through the input points.
