I was charged to try and write my own unique function , I was thinking of first sorting the array, and then writing a loop that went through each number from min(min) to max(max) but cant figure out once a repeated number is identified to skip it. Any thoughts?

That could work, but why use a for loop when there are so much more "MATLAB-ish" ways of doing it, like:
m = randi(4, 1, 11)
sortedm = sort(m)
diffs = [1, diff(sortedm)]
uniqueNumbers = sortedm(find(diffs))

out= unique(A)
Or
out=unique(A,'rows')
