You can use bubble sort:
swapped = 1;
while swapped
swapped = 0;
for i=1:numel(A)-1
if A(i+1) > A(i)
temp = A(i); A(i) = A(i+1); A(i+1) = temp; swapped = 1;
end
end
end

Here are a few ways to sort an array of unique values without using sort:
sortrows(A(:),-1)
A(end:-1:1) = unique(A);
fliplr(union(A,A(1)))
fliplr(setdiff(A,NaN))
