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

This is your 109'th question in this forum. I expect that you know how to format the code.
Do you have a good reason not to care about the readability of your question?

...
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
