Description
A general linear interpolation problem is posed and solved. This problem is
called umbral interpolation problem because its solution can be expressed by
a basis of Sheffer polynomials. The truncation error and its bounds are
considered. Some examples are discussed, in particular generalizations of
Abel-Gontscharoff and central interpolation are studied. Numerical examples
are given too.
