MATLAB: Re-arranging huge martix

Question

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

Morgan

Answer 1

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