R2026b

Rescale Laurent polynomial

Syntax

Q = rescale(P,c)

Description

Q = rescale(P,c) scales the coefficients of the Laurent polynomial P by the nonzero scalar c.

Examples

Rescale Laurent Polynomial

Create the Laurent polynomial $$a(z)=4z+6+10z^{-1}+14z^{-2}+22z^{-3}+26z^{-4}$$.

a = laurentPolynomial(Coefficients=[4 6 10 14 22 26],MaxOrder=1);

Divide the coefficients of $$a(z)$$ by 2.

b = rescale(a,1/2)

b = 
  laurentPolynomial with properties:

    Coefficients: [2 3 5 7 11 13]
        MaxOrder: 1

Input Arguments

P — Laurent polynomial

laurentPolynomial object

Laurent polynomial, specified as a laurentPolynomial object.

c — Scale factor

nonzero scalar

Scale factor, specified as a nonzero scalar.

Example: Q = rescale(P,5) multiplies the coefficients of P by 5.

Data Types: double

Output Arguments

Q — Scaled Laurent polynomial

laurentPolynmial object

Scaled Laurent polynomial, returned as a laurentPolynmial object.
