for loop as matlab function in simulink

Hello is there any way to do for loop as a matlab function in simulink. my code is as follows:

P=zeros(1,n+1 );

P(1) = P_in ;

CR = (P_out/P_in)^(1/n);

for i = 2:n

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

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

end

T=zeros(1,n);

for i = 1:n-1

T(i) = ((P(i+1)/P_in)*(T_in^(kappa/(kappa-1))))^((kappa-1)/kappa);

T(i+1) = ((P(i+1)/P(i))*(T(i)^(kappa/(kappa-1))))^((kappa-1)/kappa);

end

running=zeros(n,1);

for i=1:n

running(i)=((P(i+1)/P(i))^((kappa-1)/kappa));

end

W = (kappa*M)/(kappa-1)*((sum(running))-n);

is there any way to solve this in simulink?
