Hallo every body have this matrix as

   -4.1060   -0.0020   -4.1060   -0.0010   -4.1090   -0.0010
   -3.9950    3.2950   -3.9950    3.2960   -4.0030    3.2930
   -3.9940    3.2940   -3.9970    3.2970   -4.0010    3.2940
   -4.1060   -0.0020   -4.1080         0   -4.1060   -0.0020
   -4.1070         0   -4.1070   -0.0020   -4.1090   -0.0010
   -3.9960    3.2930   -3.9970    3.2970   -4.0030    3.2960
   -3.9970    3.2930   -4.0010    3.3050   -4.0020    3.2950
   -4.1060   -0.0020   -4.1060         0   -4.1080   -0.0010
   -4.1070         0   -4.1060         0   -4.1080         0
   -3.9860    3.2860   -3.9970    3.2970   -4.0030    3.2950
   -3.9950    3.2950   -3.9970    3.2970   -4.0030    3.2950

   -3.9950    3.2950   -3.9970    3.2970   -4.0020    3.2950

which can be of any size, now i want to place all the values so that 3rd n 4 th coulm values comes under the end of 1st and 2nd row and so on all other tow pair columns values come under first n 2nd row

Please show an example of the desired output. Why do you want to do this? Is this homework?

This cannot work for a [n x 6] matrix, because the result is not rectangular anymore. What do you want as output for:

x = [1,2,3,4,5,6] ?

I have matrix like

f =

     1     2     3     4     3     2     6     7
     1     2     3     4     3     2     6     7
     1     2     3     4     3     2     6     7
     5     6     7     8     3     2     6     7
     9    10    11    12     3     2     6     7
    13    14    15    16     3     2     6     7

and i want the result to be f3 =

     1     2
     1     2
     1     2
     5     6
     9    10

reshape([M(:,1:2:end) M(:,2:2:end)],[],2) % M is your Matrix
