t= [ 4 2
2 6
6 9]
c= [ 2
3
1]
Now, I want to arrange t according to c index; I need to get t nex sorted based on c :
t= [ 2 6
4 2
6 9]
Here is what I tried:
h=cell(1,1);
h{1,1}=t;
h{1,1}(c)
The answer I get is just one column sorted, but not the total matrix t.

You need to negate c and add 4 if you want the results you gave:
t= [ 4 2
2 6
6 9]
c= [ 2
3
1]
c2 = -c+4
h = t(c2,:)
You'll see:
h =
2 6
4 2
6 9
exactly as you requested. However, I think you may really want Cedric's solution, despite what you actually asked for.
