WebAnother important example of matrix norms is given by the norm induced by a vector norm. Definition 8. If kkis a vector norm on Cn, then the induced norm on M ndefined by jjjAjjj:= max kxk=1 kAxk is a matrix norm on M n. A consequence of the definition of the induced norm is that kAxk jjjAjjjkxkfor any x2Cn. Let us now verify (MN 4) for the ...
