I tried this but it did not work:

function [z] = compute_Euclidean_norm(x) s = x.^2; result = sum(s); z = sqrt(result);

end

Exercise 2 The Euclidean norm of an n-dimensional vector is defined as k=1 Write a Matlab function compute.Euclidean norm.m that computes the norm (2), for an arbitrary input vector r. The function should be in the following form function [2] compute-Euclidean norm(x)
