WebOct 31, 2011 · Spline interpolation uses low-degree polynomials in each of the intervals, and chooses the polynomial pieces such that they fit smoothly together. The resulting function is called a spline. For instance, the natural cubic spline is piecewise cubic and twice continuously differentiable. Furthermore, its second derivative is zero at the end … Suppose the interval [a,b] is [0,3] and the subintervals are [0,1], [1,2], and [2,3]. Suppose the polynomial pieces are to be of degree 2, and the pieces on [0,1] and [1,2] must join in value and first derivative (at t=1) while the pieces on [1,2] and [2,3] join simply in value (at t = 2). This would define a type of spline S(t) for which would be a member of that type, and also

Spline interpolation is often preferred over polynomial interpolation because the interpolation error can be made small even when using low-degree polynomials for the spline. Spline interpolation also avoids the problem of Runge's phenomenon , in which oscillation can occur between points when interpolating … See more In the mathematical field of numerical analysis, spline interpolation is a form of interpolation where the interpolant is a special type of piecewise polynomial called a spline.

I recently had the need to create a smoothed curve from a series of X/Y data points in a C# application. I achieved this using cubic spline interpolation.I prefer this strategy because I can control the exact number of points in the output curve, and the generated curve (given sufficient points) will pass through the … how to start your period immediately
