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.
