MATLAB: Multiple columns to one column

>>Hi I am kinds of practicing the matlab code to edit some data

I am trying to edit the multiple columns of data to one columns like the pictures above.

Anyone help me with this problem??

A=[1 2 3;4 5 6;7 8 9];
B=A(:)

% Or Use reshape function

B=reshape(A,[],1)

C = reshape([reshape(A,2,[]);reshape(B,2,[])],[],1);

This depends on the lengths of the column vectors A and B being the same multiple of 2.

I figured out how to do it...

    for i=1:length(S(:,1))
        fprintf(fileID, '%s ',S(i,:)');
        fprintf(fileID,'\n');
    end

Cheers!
