Of course. The simplest solution is probably the 'type' function:

    filename = "/path/to/README.txt";
    type ("-q", filename)

Another very easy way is the 'fileread' function:

    filename = "/path/to/README.txt";
    disp (fileread (filename));

Or if you like to read the file line-by-line:

    filename = "/path/to/README.txt";
    fid = fopen (filename, "r");
    while (! feof (fid))
      s = fgets (fid);
      fputs (stdout, s);
    endwhile
    fclose (fid);
