There is a trivial answer: fileread reads the entire file. But I guess that you want to split and interpret the data, but you did not mention any details unfortunately. So what is the wanted output?
s = fileread(FileName);
c = strsplit(s, ' ');
Now most of the substrings have the format "a:b", but there are two "1" also. I cannot guess, what you want as output then, but if should not be hard to obtain it - after it is defined clearly.
