RS =
           1       29374          11           6           5           7           1           4           3          10

           6       44168          12          10           4           6           3           5          11           7
           7       46220           2          11           6           5          12           3           9           8
           8       47074           8          11           1           7           5           4           6           2
           9       51854           7           8           2           5           1          12          11           4
          10       52194           7           9           2           5          11           1          10           3
         

i want to choose line 1 and 2 and 9 and 10 so i did it like this

P1 = RS(1,:)
P2 = RS(2,:)
P3 = RS(9,:)
P4 = RS(10,:)

from this i get my answer like this

P1=

1       29374          11           6           5           7           1           4           3          10

P2=

2       33444          10           2           4           6           7           1           3           8

P3=

9       51854           7           8           2           5           1          12          11           4

P4=

10       52194           7           9           2           5          11           1          10           3

however i only want to used from line 3 until last

how do i code that to that i just get my answer like this

P1=

         11           6           5           7           1           4           3          10

P2=

       10           2           4           6           7           1           3           8

P3=

        7           8           2           5           1          12          11           4

I would suggest going through chapter 5 of MATLAB Onramp. It shouldn't take too long and would really help you out.

In the meantime, the short answer is to include in your command the range of data you want to extract:

P1 = RS(1,3:end)
...
