Michel, The expression $x_i$ is ambiguous for many reasons. You don't know the type of x. It could be a vector so x_i is an element. It could be a symbol so x_i is a symbol. It could be a matrix so x_i could be a vector, etc. Without knowing the type of x (and, by the way, of i) and the domain of discourse x_i says nothing. Tim
