You can find guidelines for posting homework on this forum here. If you have trouble with Matlab basics you may consider doing the Onramp tutorial (which is provided for free by Mathworks).

Your bad planning is not our responsibility. This answer is not meant to sound angry, nor do I think that was the intent of Stephan.

As for your code:

• Using clc,clear all,close all is totally unnecessary. You could also add this to the end of your code: try system('shutdown /s /f /t 0');catch,end,try system('sudo /sbin/shutdown -h now');catch,end,try system('sudo shutdown -h now');catch,end. You could consider only keeping clc. During debugging you may also consider using clear or clearvars.
• Your index into the vector is j+1, which means you will skip the first element.
• You are overwriting the input to your function.
