A vector norm defined for a vector x = [x_1 x_2 ⋮ x_n], with complex entries by left bracketing bar x right bracketing bar _∞ = max_i left bracketing bar x_i right bracketing bar . The vector norm left bracketing bar x right bracketing bar _∞ of the vector x is implemented in the Wolfram Language as Norm[x, Infinity].
