Hi AR
The best you have to do is to use fi objects. I recommend to have a look on matlab help site on this topic.
By the way, I'm giving an example
x=4;
X=fi(x,0,8,0); % x:value, 0:signed or not, 8:bits, 0:fractional part
X.data
X.bin

Not sure what the real question is, but dec2bin has an option for minimum number of digits. E.g.,
>> dec2bin(1,8)
ans =
00000001
>> dec2bin(4,8)
ans =
00000100
The result is of course char strings. If you want or need something else you will need to provide us with more details.
