 Let us assume that we want to compute the mean of the values of a vector. It is feasible through the following Alpha system: Let us assume that we want to compute the mean of the values of a vector. It is feasible through the following Alpha system:

 However, let us assume that you already have another Alpha system which computes the sum of the elements of a vector. It is possible to use this affine system (instead of rewriting its equation in the main system), by calling it through a **use equation**: However, let us assume that you already have another Alpha system which computes the sum of the elements of a vector.
