Important: The linalg package has been deprecated. Use the superseding command LinearAlgebra[ToeplitzMatrix], instead.

- For information on migrating linalg code to the new packages, see examples/LinearAlgebraMigration.

The procedure toeplitz(L) returns the symmetric toeplitz matrix corresponding to the list L.

The matrix result has as many rows (and columns) as there are elements in the list L.  The first element of L is placed all along the diagonal, and the ith element of L is placed all along the (i-1)th sub  and super  diagonals of the result.

The command with(linalg,toeplitz) allows the use of the abbreviated form of this command.

$\mathrm{with}\left(\mathrm{linalg}\right)\:$

$\mathrm{toeplitz}\left(\left[a\,b\,c\right]\right)$

$\left[\begin{array}{ccc}a& b& c\\ b& a& b\\ c& b& a\end{array}\right]$
