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

The function vandermonde(L) returns the Vandermonde matrix formed from the elements of the list.  This square matrix has as its (i,j)th entry $L_i^{j-1}$.

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

$\mathrm{vandermonde}\left(\left[1\,2\,3\,4\right]\right)$

$\left[\begin{array}{cccc}1& 1& 1& 1\\ 1& 2& 4& 8\\ 1& 3& 9& 27\\ 1& 4& 16& 64\end{array}\right]$

$\mathrm{vandermonde}\left(\left[x\,y\,z\right]\right)$

$\left[\begin{array}{ccc}1& x& x^2\\ 1& y& y^2\\ 1& z& z^2\end{array}\right]$
