Error due to variable size data in Simulink Matlab function block

Hi all, I have a similar problem due to variable size data in Simulink Matlab function block. As a simple test, I tried to run the following code (as it is already suggested) but it doesn't work either in R2013b or R2014b version. Is there any suggestion for me?

function y = myfun(n)

coder.varsize('y', [1 100]); %n must never exceed 100

y = zeros(1,n);
