I've another problem that seems so simple but i can't figure it out. Well i can, but not in a fast way. I still have this matrix for example:
5 1
5 3
5 2
6 2.5
6 2.1
6 2.9
7 8
7 9
7 1
this matrix is ordered based on the first row. For all similar values in this first row i also want to order the values in de second row. So then you get this:
5 1
5 2
5 3
6 2.1
6 2.5
6 2.9
7 1
7 8
7 9
Looks so simple, i tried that with a combination of accumarray and sortrows..that didn't work though. Any smart people here that can help me? No more questions after this one..well maybe 1 :)
The problem was more that the collumns i want to sort are not the first two collumns, but like the 4th en 11 th collumn. I know rearranged the collumns but i bet it's possible in another way as well.

Well, you should read more carefully the help of sortrows, especially the second input.
