How to write y(n)=y(n-1)+x(n) in a way to store all values of y from n=1 to n?

How to write y(n)=y(n-1)+x(n) in a way to store all values of y from n=1 to n?

There are vectorized ways to do this, but using your formula directly:

y = zeros(size(x));
y(1) = something;  % <-- you fill this in, e.g. maybe x(1)?
n = something;  % <-- you fill this in
for k=2:n  % <-- for the rest of the elements through n
    y(k) = y(k-1) + x(k);  % <-- your formula
end
