Join Hugo J. Woerdeman, professor in the Drexel University Department of Mathematics, who will present an in-person lecture, "Optimal interpolation in Hardy and Bergman spaces: a reproducing kernel ...

Cubic interpolation fits a third order polynomial between samples. Its performance, in terms of computational speed, is intermediate between sin (x)/x and linear interpolation. The interpolation math ...

On this basis, we conclude that the Lagrange interpolation is unstable, whereas several types of piecewise low order polynomial interpolation are stable. For high order approximation with data on ...
