Laurent polynomial exponentiation
Since R2021b
Q = mpower(P,pow)
Q = P^pow
Q = mpower(P,pow) raises the Laurent polynomial P to the power pow.

example
Q = P^pow is equivalent to Q = mpower(p,pow).
Q = mpower(p,pow)

Create two Laurent polynomials:
a(z)=z-1
b(z)=-2z3+6z2-6z+2
a = laurentPolynomial(Coefficients=[1 -1],MaxOrder=1); b = laurentPolynomial(Coefficients=[-2 6 -6 2],MaxOrder=3);
Raise a(z) to the third power. Confirm the result is not equal to b(z).
a3 = a^3; a3 ~= b
ans = logical 1
Confirm a(z) raised to the third power is equal to -b(z)/2.
b2 = rescale(b,-1/2); a3 == b2
laurentPolynomial
Laurent polynomial, specified as a laurentPolynomial object.
Power, specified as an integer. If pow is negative, P must be a monomial.
Example: Q = mpower(lp,3) raises the Laurent polynomial lp to the third power.
Q = mpower(lp,3)
lp
Data Types: double
double
Laurent polynomial raised to a nonzero power, returned as a laurentPolynomial object.
Introduced in R2021b
