Could you help me write a program that answers my questions questions without using dec2hex command?

2) Create a 12-bit signed hexadecimal system. Use MATLAB to implement your algorithm in a way that it convert a given decimal x into your system. (Note: A-10, B-11, C-12, D-13, E-14, F-15). o It should display the converted x alongside a proper massage on the command window Example Output: The number x -123 is 10000000007B in a 12 bit singed hexdecimal system o Calculate the range of numbers that can be stored using your developed system. Your program should display the range of numbers at the command window. Example Output: Possible range in this system is I-100 100]
