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 ...
