Induced Norms,In many problems we shall be concerned at the same time with norms of vectors and matrices. It would seem unwise if we used completely unrelated norms for the vectors and matrices. It turns out to be convenient to have a matrix norm “.” by the vector norm. This means that we require a theorem:
