How to make number that changes as name

For example I have yi I want to make the I changes by using loops but at the same time I don't want to make it disturb the original equation like (4y_(i-1)) +(6y_(i+6)) I want it to solve part of this

Hi,

You can use cell array for this. Instead of creating a new variables every time in a loop, you could index those in a single cell array. That means, now instead of referring to y_i, you should refer this as y{i}. Your original equations should remain undisturbed.

eg. (4y{i-1}) +(6y{i+6}).

Example code.

N = 10;
y = cell(1,N);
for k = 1:N
    y{k} = k*k;         % do your changes accordingly
end

Its not recommended to name your variables dynamically. For more information, you could refer to the link below.

Hope this helps.

It's really brilliant idea but pardon me I'm still beginner in matlab how can I make that with my program I mean I have name and numbers shifting based on the loop for example whne I = 1 you can see the numbers and names as it is but when i=2 the numbers with constant and number of contacts shift by 1
