Degree of Laurent polynomial
Since R2021b
deg = degree(P)
deg = degree(P) returns the degree of the Laurent polynomial P.
deg
P
If P(z) is a Laurent polynomial P(z)=∑k=mnCkzk, where m and n are integers, the degree of P(z) is n-m.
example

Create two Laurent polynomials:
a(z)=z-1
b(z)=-2z3+6z2-7z+2
a = laurentPolynomial(Coefficients=[1 -1],MaxOrder=1); b = laurentPolynomial(Coefficients=[-2 6 -7 2],MaxOrder=3);
Multiply a(z) and b(z). Confirm the degree of the product is equal to the sum of the degrees of a(z) and b(z).
ab = a*b; degree(ab)
ans = 4
degree(a)+degree(b)
laurentPolynomial
Laurent polynomial, specified as a laurentPolynomial object.
Degree of Laurent polynomial, returned as a nonnegative integer.
