how to convert negative integers(that are not between -127 and 0) to binary in matlab?

hi. i want to convert these numbers to binary:b=[171 -7 4 -140].and i use this code: bitstream=dec2bin(typecast(int8(b),'uint8')); but it does not work correctly for numrbes that are not in this interval[-127 127] how can i convert them to binary and agian to integer correctly?

What range are they in? E.g., for a 16-bit range:

bitstream = dec2bin(typecast(int16(b),'uint16'));

You've got numbers outside the signed 8-bit range in your example, so it will simply not be possible to represent them using your 8-bit scheme. So maybe just using a 16-bit or 32-bit conversion will work for your application.
