Suppose a polynomial or convergent power series
is raised to powers j = 0, 1, 2, 3, … The coefficients of xk in [f(x)]j, k = 0, 1, 2, …, may be entered as elements in positions (j, k) in an array or matrix F, thus:
By construction all elements in column (k) have weight (sum of suffixes) equal to k.
