DEC2BIN converts non-negative decimal integers to a binary string. I want to create binary strings, with a leading sign bit, from any (negative or positive) integer.

This can be accomplished using the TYPECAST function. For example, to find a binary string for 'n' with respect to 8-bit two's complement, you can use the command,
dec2bin(typecast(int8(n),'uint8'))
