arrays within for loop

for k=1:+1:4
    S=(1/(k+1))*(m-b*y-m*r);
    I=(1/(k+1))*(a*e-(m+r)*i);
    y=y+(S*I);
end

I want to store values of S in ascending array and I in descending array then I'll get required y

can anyone help me with this code please.....

for k=1:4
    S(k)=(1/(k+1))*(m-b*y-m*r); % How to get y here?
    I(k)=(1/(k+1))*(a*e-(m+r)*i);
end
S=sort(S);
I=sort(I,'descend');
%Now Calculate Y

Or

y=zeros(1,4)
for k=1:4
    S(k)=(1/(k+1))*(m-b*y(k)-m*r);
    I(k)=(1/(k+1))*(a*e-(m+r)*i);
    y(k+1)=y(k)+(S(k)*I(k));
end
S=sort(S);
I=sort(I,'descend');
% Canculate y again % I didnot find any sense here
