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:
“Capital is a result of labor, and is used by labor to assist it in further production. Labor is the active and initial force, and labor is therefore the employer of capital.”
—Henry George (1839–1897)
“Parents ought, through their own behavior and the values by which they live, to provide direction for their children. But they need to rid themselves of the idea that there are surefire methods which, when well applied, will produce certain predictable results. Whatever we do with and for our children ought to flow from our understanding of and our feelings for the particular situation and the relation we wish to exist between us and our child.”
—Bruno Bettelheim (20th century)
