and for the display i first wrote

fid=fopen('N1RONNO.CEP','r')

disp(fid)

and i always got -1 which is wrong and now i knew why, so thnx

Yasmin Tamimi 2011-5-13

It seems like I was putting the files in the wrong directory, but now when I run the command [fid,message] = fopen('N1RONNO.CEP','r');

fid returns only one number instead of the matrix??

Walter Roberson 2011-5-13

fid will only be a file identifier. You will need to textscan() or fscanf() or the like to read the data. See Oleg's example.

在 MATLAB Online 中打开

fid  = fopen('fullpath/namefile.cep'); % In read mode by default
data = textscan(fid,repmat('%f',1,15),'Delimiter',' ');
fid  = fclose(fid);

Substitute 'fullpath/namefile.cep' with your path and the name of the file

textscan() returns a cell array.

If you change Oleg's textscan() to

data = textscan(fid,repmat('%f',1,15),'Delimiter',' ','CombineOutput',true);

then afterwards data{1} will be the entire matrix of data.

OK. now i got it. Thanx a lot for both of you.
