sorting a list by position

p=[5 3 1 7 9 2 4 6 8]

o=[0 2 4 2 4 3 1 1 3]

I want to sort o from largest to smallest, but while sorting o, the movement position of o is also applied to the same position of p when sorting

so when aftersorted o=[4 4 3 3 2 2 1 1 0]

p will become [9 1 2 8 3 7 4 6 5]

or [1 9 8 2 7 3 6 4]

where in p the number 9 and 1 can be swap and is the same because from o there are two 4's that is in the same position as p

2 and 8 could be swap

3 and 7 can be swapped

4 and 6 can be swapped

5 cannot be swapped because only 1 number

[newo, order] = sort(o, 'descend');
newp = p(order);

what is newo and newp

[Guillaume]

Your new sorted o and sorted p. You can call them whatever you want, o and p respectively if you want to replace the original vectors.
