How to print result of dec2bin to file

Example:

A = (0:255);
B = dec2bin(A);
fid = fopen('test.txt' , 'w');
fprintf(fid, '%s', B);
fclose(fid);

When you execute the above the fprintf function prints out the first column of the entire B array and then the entire second column, and so on. That is, it doesn't print the entire first binary value and then the entire second binary value and so on.

How do I fix this?

Thanks!

Answer 1

[Oleg Komarov]

fprintf(fid, [repmat('%c',1,size(B,2)) '\r\n'], B.');

The output is written columnwise, but DEC2BIN replies the string in row-orientation. Therefore transposing should solve the problem:

fprintf(fid, '%s', transpose(B));

Thanks Oleg!

Hi Jan,

The solution you gave worked except for the fact that it just printed out one gigantic long concatenated string of all the binary values as opposed to having each binary value on its own line like Oleg's did.

Thanks to both of you for your help! I really appreciate it. :)

Use

fprintf(fid, '%s\n', transpose(B));

if you want different lines. Your original code that Jan was going on would have put everything on the same line.
