WebCubic Hermite Interpolation • Develop a two data point Hermite interpolation function which passes through the func-tion and its first derivative for the interval [0, 1]. • Therefore and . • We must impose constraint equations (match function and its derivative at two data points). • Therefore we require a 3rd degree polynomial. 0 x f f 1 WebBecause of its oscillation property the LAGRANGE polynomial is not suitable to interpolate the given experimental data. Thus, the spline interpolation has been discused as an alternative approach.
