fid = fopen('gobang_no_aircon_20130729.dat', 'r');
datacell = textscan(fid, '%g%g%g%g%g%g', 'headerlines', 1, 'collect', 1);
fclose(fid);

data_array = datacell{1};

>> fid = fopen('gobang_no_aircon_20130729.dat','r');

>> datacell = textscan(fid, '%g%g%g%g%g%g','headerlines', 1 , 'collect', 1);

I put just like this, but I got

*??? Error using ==> textscan Invalid file identifier. Use fopen to generate a valid file identifier. *

what is my problem??

You must not have a file named gobang_no_aircon_20130729.dat in your local directory. Try

data_array = 'file not opened';

[fid, msg] = fopen('gobang_no_aircon_20130729.dat','r');
if fid < 0; fprintf('open failed because: %s\n', msg);
else
  datacell = textscan(fid, '%g%g%g%g%g%g', 'headerlines', 1, 'collect', 1);
  fclose(fid);

    data_array = datacell{1};
  end

I got

??? Error using ==> textscan Unknown option 'collect'.

what is it..?

[Walter Roberson]

You might have to spell it out in full; it is 'CollectOutput'

[hyunmin]

I already put collectOutput but it said "bad string"

@hyumin: If you read the documentation of textscan(), you will find all required information. It would not be efficient to ask Walter to re-tell, what you can read there.
