    Open Live Script

    Create two Laurent polynomials:

    • a(z)=6z-2

    • b(z)=z3/6

    lpA = laurentPolynomial(Coefficients=[6],MaxOrder=-2);
lpB = laurentPolynomial(Coefficients=[1/6],MaxOrder=3);

    Create the Laurent matrix [a(z)11b(z)].

    lmat = laurentMatrix(Elements={lpA 1; 1 lpB});

    Obtain the determinant of lmat. Confirm the determinant is z-1.

    d = det(lmat)
    d = 
  laurentPolynomial with properties:

    Coefficients: [1 -1]
        MaxOrder: 1

    Input Arguments
