for i = 1:2
Result(i) = norm(vcu(i,:))
end
p=0
for k = 1:2
ada = vcu(k,:)/Result(k)
end
Where vcu is a vector (a,b,c;a2,b2,c3)
when I run the code I get 2 1x3 vectors as ada but when I want to use ada further in my code it does not work because ada is only saved for k=2

ada(k) = vcu(k,:)/Result(k)%I think you just need to index ada.

Here are a few pointers which may help with your situation:
  • As per the code given above each iteration of the for loop causes the result to be saved in the variable ada, which essentially overwrites the existing value. Since ada is not predefined, it takes the size of the last data assigned to it (1x3).
  • Instead, you may use the following code:
ada = zeros(2, size(vcu, 2));
for k = 1:2
ada(k,:) = vcu(k,:)/Result(k);
end
