For any two matrix norms and , we have that: for some positive numbers r and s, for all matrices . In other words, all norms on are equivalent; they induce the same topology on . This is true because the vector space has the finite dimension . Moreover, for every vector norm on , there exists a unique positive real number such that is a sub-multiplicative matrix norm for every .

of the matrix norm, we can replace the "sup" with "max" and write A A X X p X X p p X p p = = ≠ = max maxr Ar r r r 0 1. (4-6) When computing the norm of A, the definition is used as a starting point. The process has two steps. 1) Find a "candidate" for the norm, call it K for now, that satisfies A X p X p r r ≤ K for all X r. 2) Find at least one nonzero X r
