DI COSTANZO commented on MATH-683:
----------------------------------
Effectivelly, the code you posted above can be a solution for someone who only
want to evaluate a polynomial function shifted by a specific value.
Unfortunately, I can't deal with that representation, as I need to have the
coefficients of the shifted polynomial :
I'm facing this problem in a recurrence formula. To achieve it, I need to sum
polynomial, some of them being shifted by real values.

> Create a method shift to transform a polynomial P(k) in P(k + a) where a is
> any double value.
> The polynomial sum(ai * k^i) turns into sum(ai * (k+a)^i)
