Talk:MATLAB Programming/Advanced Topics/Advanced IO/Reading and writing from files

i have proble with fopen I write this line  binary read access matlab return evry time I run the line a values upper or egal than 3, that means the file is right open but the files is not open at my windows , I also use the permission 'rt'[fopen('statut.xls','rt')] to read the file as txt and the file was not appear in my windows. I don't know why any file appear at window despite the fact that fopen return a good file identifier.
