2. [10pts) The magnitude (norm) of a vector = x + y + zk is calculated by || | = x2 + y2 + 2. Write a MATLAB script that asks and accepts the xy, and value from the user from the Command Window and returns the magnitude of the vector. The x, y, and z values must be entered as a single 1D array, i.e. (x y z] or [x; y: z]. Name your script as Lastname Norm.m and submit the file in the Dropbox. Make sure your program include proper comments
