Breaks

The break sequence is assumed to be strictly increasing,

• breaks(1) < breaks(2) < ... < breaks(l+1)
  

with l the number of polynomial pieces that make up .

While these polynomials may be of varying degrees, they are all recorded as polynomials of the same order k, i.e., the coefficient array coefs is of size [l,k], with coefs(j,:) containing the k coefficients in the local power form for the jth polynomial piece, from the highest to the lowest power; see (*) below.
