Description

[Error using fseek Invalid file identifier. Use fopen to generate a valid file identifier.]


my file is in the path but when i use fseek it turns uo the problem.


My code is shown as below:

dataNO = 50400; fileNO = 1; point = 0; finish = 50400;

dataBin = double(dataNO); fn = ('C3trace%05d.trc'); null ~= ('C3trace%05d.trc');

for j=0:1:fileNO s = sprintf(fn,j); fid = fopen(fn,'r','b');
if fid == null fprintf('Cannot open %s files \n',fn); system(pause) end

end

fseek(fid,0,'bof');
