Vander(V) = Vandermonde's matrix from vector V
Vander(V) = Vandermonde's matrix from vector V:
Let V be a row or column vector with elements v1, v2, v3, ..., vn. Vandermonde's
matrix of V is
{1, v1, v1^2, ..., v1^(n-1);
1, v2, v2^2, ..., v2^(n-1);
...
1, vn, vn^2, ..., vn^(n-1)}
It is nonsingular if vi != vj for all i and j <= n.
