The size of the indicated variable or array appears to be changing with each loop iteration

hello, i am trying to model an iteration loop in matlab, and i am getting the following error 'The size of the indicated variable or array appears to be changing with each loop iteration'. is there a way to solve it?

mz code is:

for i = 2:n

CR = (P_out/P_in)^(1/(i+1));

P(1) = P_in;

P(i) = CR*P(i-1);

P(i+1) = CR*P(i);

end

[JESUS DAVID ARIZA ROYETH]

P=zeros(1,n+1);
P(1) = P_in;
for i = 2:n
    CR = (P_out/P_in)^(1/(i+1));
    P(i) = CR*P(i-1);
    P(i+1) = CR*P(i);
end
