arranging matrix elements in descending order

I want max value in every column so i have used max command .That was helpful.but i want to find the next maximum value in all the columns.This process have to be repeated till finding the least value in that column.i mean in descending order.for ex x=[1 2 3;4 5 6;7 8 9] max(x) will give (1 4 7) [x,y]=max(x) y gives (1 1 1) (indices)

next i have to find next max (2,5,8) the indices i should get (2 2 2) what command i should use?
