Given a series of objects x variables matrices with a common structure, we show how to express that structure by a vector whose components correspond to the matrices. Moreover F tests may be derived for hypothesis on this structure vectors for matched series of matrices. We show also how to apply multiple comparison methods whenever significant differences between structure vectors are found. Namely, the very robust Scheffe's method was considered as well as Tukey's method.
