Hey everybody, I have some binary information, like a=[11110000 00001111 00000000 11111111], I want to write them to a text file. i tried with fprintf and fwrite but i couldn't! anybody has such a experience? Thanks a lot in advance. best.

I would say that is it stored as a 1*4 array of 8 bits binary data I mean instead of [0 4 8 16] I would to show my data like [00000000 00000100 00001000 00010000]

I tried all the above forms, but i didn't work! I want to save my binary inputs. and these inputs are 8 bits data. actually they're complex, I mean the first 4 bits, real part and the last 4 bits img part. and after saving these inputs in a text file, I am going to separate the rael and imaginary part for furthure calculation. so i need these information to be saved as binary, as array of 8 bits.

a=[11110000; 00001111; 00000000; 11111111]; dlmwrite('C:\Users\dell\Desktop\a.txt',a);

t = cellstr(dec2bin(a, 8));
fid = fopen('a.txt', 'wt');
fprintf(fid, '%s\n', t{:});
fclose(fid);

That is not going to work.
>> ['11111111' , '00000000' , '10101010']
ans =
111111110000000010101010
Remember, [] is concatenation for strings. {} is for string arrays.

yo are right, it should be like: [ '11111111' ; '00000000' ...
