WebWell, look at. M = [ 1 0 0 0] . The result of multiplying this by [ 1, 0] t has length 1; the result of multiplying it by [ 0, 1] t has length zero. And each of these vectors has length one. So you're looking for something that can multiply 1 to get 0 in one case, and can multiply 1 to get 1 in the other. 1) for all positive integers r , where ρ (A) is the spectral radius of A . For symmetric or hermitian A , we have equality in (1) for the 2-norm, since in this case the 2-norm is precisely the spectral radius of A . For an arbitrary matrix, we may not have equality for any norm; a counterexample would be A = [0 1 0 0] , … Ver mais In mathematics, a matrix norm is a vector norm in a vector space whose elements (vectors) are matrices (of given dimensions).
