Hi,
it looks like Maxima doesn't have any polynomial interpolation support,
am I wrong ? In a software like Pari/GP, there is :
> ?polinterpolate
polinterpolate(xa,{ya},{x},{&e}): polynomial interpolation at x according to
data vectors xa, ya (ie return P such that P(xa[i]) = ya[i] for all i). If ya
is omitter, return P such that P(i) = xa[i]. If present, e will contain an
error estimate on the returned value.
> polinterpolate([0,1,4,9,16,25,36])
%45 = x^2 - 2*x + 1
Is there really nothing like that in Maxima ?
Regards,
