function C = lp2num(P) %LP2NUM Coefficients of a Laurent polynomial object. % C = LP2NUM(P) returns a vector C whose elements are % the coefficients of the Laurent polynomial object P. % % If L is the length of the vector C, P represents % the following Laurent polynomial: % P(z) = C(1)*z^d + C(2)*z^(d-1) + ... + C(L)*z^(d-L+1) % where d = powers(P,'max') % % See also GET. % M.
