Hello,

I need to generate strings, 4 characters long that include either '0' (zeros) or '1' ones.

I do:

for m=0:15 '(4 bits)
q=dec2bin(m);
s1=substr(q, 1, 1);
s2=substr(q, 2, 1);
s3=substr(q, 3, 1);
s4=substr(q, 4, 1);
end
substr is the equivalent of mid$(a$,..) in visual basic. Is there any similar function in matlab?
since by default, for some m, q does not include the leading zeros, it does not work.

Any ideas about how to make q 4 character long and retain the leading zeros?

Thanks

Tuli

q = dec2bin(0:15);
num2str(q) % transform in char
