This Iterative algorithm is used for grouping of vectors. Input: a set of vectors {Xn є D}, number of groups-P.Output: a set of vectors {Xn є D}, which are labeled by (1…P).
This Iterative algorithm offers a statistical model for a set of vectors.Input: a set of vectors {Xn є D}, number of groups-P, expectations of
each group, empiric probability, empiric variances.Output: a set of vectors {Xn є D}, which are labeled by (1…P).
