Initial Values
The initial values of columns can be calculated by first manually calculating N consecutive values of the function and by backtracking, i.e. calculating the required differences.
Col gets the value of the function at the start of computation . Col is the difference between and ...
If the function to be calculated is a polynomial function, expressed as
the initial values can be calculated directly from the constant coefficients a0, a1,a2, ..., an without calculating any data points. The initial values are thus:
- Col = a0
- Col = a1 + a2 + a3 + a4 + ... + an
- Col = 2a2 + 6a3 + 14a4 + 30a5 + ...
- Col = 6a3 + 36a4 + 150a5 + ...
- Col = 24a4 + 240a5 + ...
- Col = 120a5 + ...

Famous quotes containing the words initial and/or values:
“No punishment has ever possessed enough power of deterrence to prevent the commission of crimes. On the contrary, whatever the punishment, once a specific crime has appeared for the first time, its reappearance is more likely than its initial emergence could ever have been.”
—Hannah Arendt (1906–1975)
“Everyone values the good nature of a man with a gun.”
—Mason Cooley (b. 1927)
