The natural norm induced by the L^∞-norm is called the maximum absolute row sum norm and is defined by left double bracketing bar A right double bracketing bar _∞ = max_i sum_(j = 1)^n left bracketing bar a_(i j) right bracketing bar for a matrix A. This matrix norm is implemented as Norm[m, Infinity].
