Embedded matlab function error

Hello!

How can I resolve this error:

"Computed maximum size of the output of function 'eye' is not bounded.
Static memory allocation requires all sizes to be bounded.
The computed size is [:? x :?]."

I use this code:

function y = fcn(a,b,c)
I = eye(a);
y = 1;
end

(I show u the worst part of my code)

I tried to use this one:

function y = fcn(a,b,c)
  coder.varsize('I', [10 10]);
  I = eye(a);
end

But it is still not working...

Any ideas?

Thx!

Oh, i used this:

N = 10000;
assert(a< N);
I = eye(a);

It is working!

Try

function y = fcn(a,b,c)
  I = zeros(10,10);
  I = eye(a);
end

Still the same.. Can I control size of matrix from external sourse?
