use matlab script without any loops

2. [10pts) The magnitude (norm) of a vector u = xi + yj + zk is calculated by ||0|| = x2 + y2 + z2 Write a MATLAB script that asks and accepts the x, y, and z 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; 2). Name your script as LastnameNorm.m and submit the file in the Dropbox. Make sure your program include proper comments
