Non-constant expression or empty matrix

Hi,
I have this error in Coder when am converting the following code, in the last line:
if ~isempty(coder.target)
coder.varsize('lattice', [100 100]);
lattice = zeros(0,0);
end
...
lattice = init_lattice(points,i);
if ~isempty(coder.target)
proposed_lattice = { 0 0 0 0 };
coder.varsize('proposed_lattice');
energy = zeros(4);
end
for j=1:4
proposed_lattice{j} = grow_lattice(lattice,points,j);
energy(j) = lattice_energy(proposed_lattice{j},points);
end
[~,min_idx] = min(energy);
if energy(min_idx) < previous_energy
lattice = proposed_lattice{min_idx};
...
'lattice' grows in size after each reassignment. First assignment by 'init_lattice' makes it 3*3, but as I understand, 'varsize' allows it to grow until 100*100. Would appreciate any clues.

I would be more comfortable if you defined energy with two parameters to zeros .zeroes(4) is 4x4 but you are assigning to it like it was 1d column vector.
