I am getting an error for the below eqn . I wrote coding in matlab function (user defined function in simulink),so please help with this.I have also attached my simulink model.

function y = fcn(h,u) 
A = [0 1;-1 1];
B = [0;1];
N = 300;
y = zeros(1,500);
t = 0:25
for i = 1:N
y = (h/N)*exp(i*A*(h/N)).*B*u(t-(i*(h/N)));

function y = fcn(h,u) 
A = [0 1;-1 1];
B = [0;1];
N = 300;
y = zeros(1,500);
t = 0:25
for i = 1:N
y(i)= (h/N)*exp(i*A*(h/N)).*B*u(t-(i*(h/N)));
end
y
end

You left two ends at the end missing

@Madhan: the code overwrites y in every single run of the Loop.
