DEFINITION MODULE VanderM;

   PROCEDURE Vander(X, W, Q: LVector); 
   (*
     Solves the Vandermonde linear system [(sum (i=1) to (n)) xi^(k-1)wi = qk]; 
     (k=1,...,n). Input consists of the vectors X[n] and Q[n]; the vector W[n] 
     is output. Double precision is a good idea for this routine.
