MATLAB: Need shrter code

Question

hi,

can anybody make these code shorter and faster?

Nofusers=17856;
k1 = 1;
f1 = fopen('d:\matlab11\bin\flixster_time\ratings_tf\len_flix1.txt');
c = fscanf(f1,'%d');
fclose(f1)
ini = 1;
f   = fopen('d:\matlab11\bin\flixster_time\ratings_tf\flix_fin.txt');
cod = fscanf(f,'%d');
for i = 1:17856
  k = 1;
  for j = ini:c(i)+ini-1
    celcod{i}(k) = cod(j);
    k = k+1;
  end;
  ini = ini + c(i);
end

thanks

...
celcod = cell(1, 17856);  % Pre-allocate!
ini = 1;
for i = 1:17856
  celcod{i} = cod(ini:c(i)+ini-1);
  ini = ini + c(i);
end
