Vandermonde matrix : vandermonde

vandermonde takes as argument a vector whose components are denoted by xj for j = 0..n - 1.
vandermonde returns the corresponding Vandermonde matrix (the k-th row of the matrix is the vector whose components are xik for i = 0..n - 1 and k = 0..n - 1).
Warning !
The indices of the rows and columns begin at 0 with Xcas.
