create indexes of x in a for loop

Hi all, I am trying to create and save some x values in an array in a format of A=[x(2)+x(3);x(3)+x(6);x(4)+x(9)];
so I tried something like that
for i=1:3
y=@(x) x(i+1)+x(3*i);
end
however I get for each i the same expression,
y=@(x)x(i+1)+x(3*i)
Is there any way to do that?
thanks
Nikolas

It is not very clear what you are trying to achieve, but it is possible to store a function handle in a cell array:
C = cell(1,3);
for k=1:3
C{k} = @(x) x(k+1)+x(3*k);
end
Although to be honest it is not clear why you are defining a function handle at all. If x is already defined, why not just get the numeric values directly:
N = nan(1,3);
for k=1:3
N(k) = x(k+1)+x(3*k);
end

"anyway my problem if there is any way to do symbolic indexing"
What exactly is "symbolic indexing"?
Perhaps a simple function of x is what you are looking for... nothing to do with indexing at all.
