Piecewise polynomial details
[breaks,coefs,l,k,d] = unmkpp(pp)
[breaks,coefs,l,k,d] = unmkpp(pp)
extracts,
from the piecewise polynomial pp
, its breaks breaks
,
coefficients coefs
, number of pieces l
,
order k
, and dimension d
of
its target. Create pp
using spline
or
the spline utility mkpp
.
This example creates a description of the quadratic polynomial
as a piecewise polynomial pp
, then extracts
the details of that description.
pp = mkpp([-8 -4],[-1/4 1 0]); [breaks,coefs,l,k,d] = unmkpp(pp) breaks = -8 -4 coefs = -0.2500 1.0000 0 l = 1 k = 3 d = 1
