Creation of vectors in for loop and save those and fill vector up with new column vectors

Hello!

Is there a way, lets say, if I have a for loop where for every iteration it creates two column vectors, A=[1 1 1] and B=[2 2 2]

If i now want to save those two in every iteration , let say, V=[A B]

When I come in to next iteration I want to save those from the first iteration so it fills up, so iteration two I create A’ and B’ so I want the following result,

V=[A B A’ B’], where A, B, A’, B’ are column vector. So for this example I get for example,

V=[ 1 1 1; 2 2 2; 1’ 1’ 1’; 2’ 2’ 2’];

Hello,

This can indeed be done:

V = [];
for ...
   A = [...];
   B = [...];
   V = [V A B];
end

Hope this helps!

If you want to be memory efficient, you can do:

n = number of iterations;
V = zeros(1,n*6);
for i = 1:n
   A = [...];
   B = [...];
   V(6*i-5:6*i) = [A B];
end

Good luck!
