WebAug 15, 2015 · Yes. This is the way to do this. A piecewise cubic Hermite interpolant has the nice property that it is simply assured to be both continuous and differentiable across the break points, because the value and first derivative at each end of an interval is given. This is, IMHO, a very pretty way to build up a piecewise cubic. – WebInterpolation Calculator. Interpolate using linear, polynomial and cubic spline interpolation.

WebJun 22, 2024 · Spline Interpolation, especially Cubic Spline Interpolation, is a more flexible alternative that finds a piece-wise polynomial. This allows reducing the order of the polynomials used, with the advantage of being simpler and closer to reality. This comes at the price of using many polynomials in a piece-wise function rather than defining one ...
