Hello!
I have a vector a = 1:8 and want all different combinations of these numbers where each number can only occur once in each row. So i want
12345678
12345687
12345867
12345876
and so on.
I've been stuck on this for hours, I have googled and used allcomb but that leads to rows like 11111118 and I can't seem to figure out how to only get the rows where each number is represented only once. Can anyone help me?

You need permutations not combinations (which my function allcomb returns).
Take a look at PERMS
>> perms(1:3)
3 2 1
3 1 2
2 3 1
2 1 3
1 3 2
1 2 3
