ctranspose

Laurent matrix transpose

Since R2021b

Syntax

B = ctranspose(A)

Description

B = ctranspose(A) returns the transpose of the Laurent matrix A.

Examples

Laurent Matrix Transpose

Create two Laurent polynomials:

• $$a(z)=2+4z^{-1}+6z^{-2}$$

• $$b(z)=z^2+3z+5$$

lpA = laurentPolynomial(Coefficients=[2 4 6]);
lpB = laurentPolynomial(Coefficients=[1 3 5],MaxOrder=2);

Create the Laurent matrix lmat = $\left[\begin{array}{cc}-1& \mathit{a}\left(\mathit{z}\right)\\ \mathit{b}\left(\mathit{z}\right)& 7\end{array}\right]$.

lmat = laurentMatrix(Elements={-1 lpA; lpB 7});

Display the elements of the transpose of lmat.

lmatTrans = ctranspose(lmat);
for j=1:2
    for k=1:2
        elt = lmatTrans.Elements{j,k};
        fprintf("===================\nlmatTrans(%d,%d):\n",j,k);
        elt
    end
end

===================
lmatTrans(1,1):

elt = 
  laurentPolynomial with properties:

    Coefficients: -1
        MaxOrder: 0

===================
lmatTrans(1,2):

elt = 
  laurentPolynomial with properties:

    Coefficients: [1 3 5]
        MaxOrder: 2

===================
lmatTrans(2,1):

elt = 
  laurentPolynomial with properties:

    Coefficients: [2 4 6]
        MaxOrder: 0

===================
lmatTrans(2,2):

elt = 
  laurentPolynomial with properties:

    Coefficients: 7
        MaxOrder: 0
