The density of such functions in C0 (for the supremum norm) allows us to extend this result to any f in C0. We shall write Σn=−∞+∞f(2Jn)ϕJ,n+Σj=−∞JΣn=−∞+∞dj[n]Ψj,n, which means that [{φJ,n}n
(i.e. the functions coincide at each point). The interpolating polynomial of the least degree is unique, however, and it is therefore more appropriate to speak of “the Lagrange form” of that unique polynomial rather than “the Lagrange interpolation polynomial”, since the same polynomial can...
