General approach to function approximation

Abstract

Having a function f and a set of functionals \Cn\, cnf Cn (f), one can interpret function approximation very generally as a construction of some function ANf such that cnf = Cn (ANf ). All known approximations can be interpreted in this way and we review some of them. In addition, we construct several new expansion types including three rational approximations.
