Setting matrix with functions or for loop

I have a matrix as A=[1 3 5 8; 9 10 12 25; 32 21 45 65; 2 37 17 2] and I want to change places of them, B=[1 3 5 8 9 10 12 25;32 21 45 65 2 37 17 2] how can I make this code with for loop? and after this settings,I want to write this matrix to text file with tab between coloums..please help

How general does this need to be? And why do you want to use a loop specifically? This does what you're asking, and would generalize to any number of rows (as long as it's even):

B = [A(1:2:end,:),A(2:2:end,:)]
dlmwrite('filename.txt',B,'\t')
