— Function File: [x, p, n, k, d] = unmkpp (pp)

Extract the components of a piece-wise polynomial structure pp. These are as follows:

x
Samples points.
p
Polynomial coefficients for points in sample interval. p (i, :) contains the coefficients for the polynomial over interval i ordered from highest to lowest. If d > 1, p (r, i, :) contains the coefficients for the r-th polynomial defined on interval i. However, this is stored as a 2-D array such that c = reshape (p (:, j), n, d) gives c (i, r) is the j-th coefficient of the r-th polynomial over the i-th interval.
n
Number of polynomial pieces.
k
Order of the polynomial plus 1.
d
Number of polynomials defined for each interval.
