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.
