In one compiuter this code works well but in other not.

Error using textscan

Invalid file identifier. Use fopen to generate a valid identifier.

That tells you that the file name you passed into fopen() could not be found or was unreadable. This is not a textscan() issue: this is because you failed to check the return of fopen() in case of failure.

filename = 'TheFileNameGoesHere';
[fid, msg] = fopen(filename, 'rt');
if fid < 0
    error('Failed to open file "%s" because "%s"', filename, msg);
end
