Laurent matrix determinant
Since R2021b
d = det(A)
example
d = det(A) returns the determinant of the Laurent matrix A.
d
A

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.
lmat
d = det(lmat)
d = laurentPolynomial with properties: Coefficients: [1 -1] MaxOrder: 1
laurentMatrix
Laurent matrix, specified as a laurentMatrix object.
laurentPolynomial
Determinant of the Laurent matrix, returned as a laurentPolynomial object.
Introduced in R2021b
