Hello, I use the matlab coder to create a dynamic lib from matlab code. I will like to use static memory allocation. However, I get a compilation error for a piece of code. The code is simplified.

out = function (s)
size_s = size(s,2);
start = 1;
for i=1:size_s
....
bracket_end = bracket_end + 1;
if ()
break;
end;
end;
store =[start:brack_end]'
s(1,store) = [...];

An error pop-ups that the size of s is unbounded. So I try to use the assert like

assert(size(store,2) < 10000); % 10000 >> size (s,2);

This is not solving the problem. Then I have use the coder.var_size('data', [1, size(s,2)]), but this does not solve the problem. I'm using matlab 2015b. How can I solve the problem?

Thanks in advance, Clemens
