Well, I can give you a hint. Use the function dec2bin. It creates a
binary string from a decimal number. The tricky part is that it writes a
string which must then be manipulated appropriately for your purposes.
This works for me, but I'd like to hear expert opinions:
for i=0:255, x(i+1,:)=sprintf("%08i",str2num(dec2bin(i))); end
That puts the strings in a matrix called 'x'. What I'm doing is
converting the binary strings back into integers, then I change them back
into strings with appropriate padding of zeros in front. It seems kinda
messy but it works.
