WebCubic spline interpolation is a useful technique to interpolate between known data points due to its stable and smooth characteristics. Unfortunately it does not prevent overshoot at intermediate points, which is essential for many chemical engineering applications. This article presents a new interpolation method that WebLet’s use this insight and consider the popular cubic case (quadratic case is de-veloped in HW5). Cubic Spline Mimicking the form of the piecewise linear interpolant, in this case …

WebThe fundamental idea behind cubic spline interpolation is based on the engineer ’s tool used to draw smooth curves through a number of points . This spline consists of weights attached to a flat surface at the points to be connected . A flexible strip is then bent across each of these weights ,resulting in a pleasingly smooth curve . ez mix 76000WebThis is, more precisely, the cubic spline interpolant with the not-a-knot end conditions, meaning that it is the unique piecewise cubic polynomial with two continuous derivatives with breaks at all interior data sites except for the leftmost and the rightmost one.
