fill a vector inside a cycle

I have a script where I have to fill a vector like this example:
heads = (1:10);
vector_to_fill = zeros(1,5);
for i = 1 : heads
if condition
vector_to_fill(what index) = heads(i);
end
end
my problem is that I don't know what index putting to that vector_to_fill.how can I slide that vector correctly? If i put the same index as i I leave zeros between element.

clear
heads = 1:10;
k=0
for ii = heads
if rand(1,1)>0.5
k=k+1
vector_to_fill(k) = heads(ii)
end
end
