2.1 Interpolation polynomial and its calculation
Let f be a real function of a real variable (or, which makes no difference, a complex function of a complex variable). We assume that we know the values of f (x
0
), f (x
1
), ..., f (x
n
) and we look for a polynomial P such that :
P is said to be the interpolating polynomial of f (or to interpolatef ) in x 0 ...
