fwrite and fread data of multiple precision to binary file

3 次查看(过去 30 天)
Can anyone help me? fwrite and fread values are different. My trail is given below. i need to only read the sq values.
Thanks
r=1:100;
sq= sqrt(r)
fid = fopen('binary','w'); % Opening the file to write
%
if fid~=1
fwrite(fid, 8, 'uint8');
fwrite(fid, 'Table', 'char');
fwrite(fid, sq, 'float64');
fclose(fid);
end
fileid = fopen('binary','r');
if fileid~=1
equa = fread(fileid, 'float64');
fclose(fileid);
end

You need to fseek() to skip the first 6 bytes of the file.
