I want to change the r value to k value and vice versa for k value at the end of each loop. for example according to the following example, r and k are 4 6 8 10 at the end of first loop but i want k as 6 8 10 12. so after that for the second loop r will add up with 5 and k will add up with 3 and again the variables will change. how can i do this implementation?
abc=[1 3 5 7]
for t=1:3
k=abc+3
r=5+abc
r=k
k=r
end
k = 4 6 8 10
r = 6 8 10 12
r = 4 6 8 10
k = 4 6 8 10
k = 4 6 8 10
r = 6 8 10 12
r = 4 6 8 10
k = 4 6 8 10
k = 4 6 8 10
r = 6 8 10 12
r = 4 6 8 10
k = 4 6 8 10

abc = [1,3,5,7];
k = abc;
r = abc;
for ii = 1:5
[r,k] = deal(k+3,r+5)
end
r = 1×4
4 6 8 10
k = 1×4
6 8 10 12
r = 1×4
9 11 13 15
k = 1×4
9 11 13 15
r = 1×4
12 14 16 18
k = 1×4
14 16 18 20
r = 1×4
17 19 21 23
k = 1×4
17 19 21 23
r = 1×4
20 22 24 26
k = 1×4
22 24 26 28

@Kerem Yüksel: without more specific details or examples, it sounds like you should use one matrix and indexing.
