Harish - one (not so efficient) way is to check each bit in the unsigned integer. If it is a one, then write a one to your string, else write a zero. Use class to determine the data type (uint8, uint16, etc.) and the number of bits to loop over. Use bitshift on your mask (which starts at one) to shift the one bit in the mask to the left at each iteration of your loop, and use bitand on your integer and mask to see if the bit in question is a one or not.

q = quantizer('fixed', 'Ceiling', 'Saturate', [5 4]) num2bin(q,yourvariable); in above example num2bin convert your variable in a fixed point manner. total of five bits but last four bit is in fractional part.
