You can find a list of functions that can read textfiles here:
I would recommend that you use textscan, which can also convert the string data to the numeric values. However that sample file is a bit mixed-up, and does not have a simple layout. You might need to read the first part of the file line-by-line using some low level functions, and then the rest of the file using textscan. Here is a list of the low-level file-reading functions:
you might find fgetl very useful for this purpose!
Also note that if you keep a file open then (most of) these functions continue to read the file from the point where the last function finished, so you can do things like this:
fid = fopen(filename,'rt');
A = fgetl(fid);
B = fgetl(fid);
C = textscan(fid,...);
...
fclose(fid);
