I have tried searching for similar problems, but none of them seem to make sense. Now I am of course not asking for you to solve this for me, but rather if you could give me a hand in starting to tackle the problem. I personally have started using matlab only last week, so I am rather inexperienced, but I have enough time on my hands to struggle.
