Hi I want to combine two matrix(matrix1= e1(743,7), matrix2= e2(743,7)), in the form of taking the first column of the first matrix and then the first from matrix2 then again the first from matrix1 and the second from matrix2 and so on. =>
e=[e1(:,1),e2(:,1),e1(:,1),e2(:,2)...,e1(:,1),e2(:,7),e1(:,2),e2(:,1)...,e1(:,2),e2(:,7),...,e1(:,7),e2(:,1)...e1(:,7),e2(:,7)]
Can somebody helps me how to create such a matrix e which is than a 743:49 matrix?

Is there a reason you don't want to use a loop to do this?

No my problem is I'm not so sure how to program this. I mean the following isn't correct.
for i=1:7
for s=1:7
e(:,i+s)=[e(:,i),e(:,s)];
end
end
There I get the wrong solutions.

e = reshape([reshape(repmat(e1,7,1),[],49);repmat(e2,1,7)],[],2*49);

Another way:
[y x] = ndgrid((1:7)+7,(1:7));
z = [x(:)';y(:)'];
ee = [e1 e2];
e = ee(:,z(:));
