Re-arranging huge martix

Hi guys, spent long time trying to figure out how to rearange the matrix that I have, what am having is the following martix

A= [ x1 y1 x2 y2 x3 y3 ; x4 y4 x5 y5 x6 y6]

am trying to arrange my matrix into the following form B = [x1 y1 ; x2 y2 ; x3 y3 ; ....]

my original matrix is (10,1300) am trying to convert it to (6500,2)

i have tried to use for loop but it did not work out

here is my script

     A = input('enter mat>');

rowA= size(A,1);
colA= size(A,2);
n=numel(A)/2;

for i=1:1:rowA
    for j=1:2:colA-1

              B = A(i,[j,j+1])
          %continue
      end
  end

please i need something more efficient and faster than for loops!

Thanks

B = transpose(reshape(transpose(A), 2, []));

Thank you Jan

By the way, a 13000 element array is not huge anymore. A garden variety digital image will be 300 times that size.

It's pretty huge, considering you have to type the whole thing in at that prompt. ;-)

You can let the java robot do the typing for you. Then it is small again.
