How to sort each row of 120x200 array and keep track of column number ?

 I have 120x200 array ,  I want to sort each row but I need to keep column number of each entry. so let's sey it is my array :

7 8 2 1  
3 9 6 5
5 2 1 9
this should be 
1 2 7 8
3 5 6 9
1 2 5 9
and also I need to use old column number of each term ,for example 7 was in column 1 .
How can I do this in matlab (I can do sorting ,but problem is keep track of column numbers)

Use the second output of SORT:

A = [7 8 2 1 ; 3 9 6 5 ; 5 2 1 9]
[Asorted, OrigColIdx] = sort(A,2)
