WebMatrix norms. The norm of a square matrix A is a non-negative real number denoted A . There are several different ways of defining a matrix norm, but they all share the following properties: A ≥ 0 for any square matrix A . A = 0 if and only if the matrix A = 0 . ∥ k A ∥ = k ∥ A ∥ , for any scalar k . ∥ A + B ∥ ≤ ∥ A ∥ ... 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.
