There is no need to manipulate the format string, it is much simpler to use the '*' option:
>> sprintf('%0*d',4,12)
ans = 0012

With this, will you be able to work out the function?
>> sprintf('%04d',12)
ans =
'0012'

sprintf? Describing what you want in words would help
number = 12;
chars = 4;
formatstring = sprintf('%%0%dd', chars); %create format string %0{char}d' where {char} is the value of char
sprintf(formatstring, number)
