Can someone help me how to add 2 hexadecimal numbers? I would appreciate the help and sentiment.
I tried using: c=dec2hex(hex2dec(a)+hex2dec(b)));
But it didn't work. Is there a correct way to do this?

Hi Jed Louise Lesma,
Despite the extra bracket in your code (I removed it), the method you tried should work:
a = '3afb';
b = '2839';
c=dec2hex(hex2dec(a)+hex2dec(b));
Kind regards,
Robert

The "hex"-values are supposed to be given as char. Thus the str2double()-command should be deleted.
Kind regards,
Robert

>> 0x3afb + 0x2839
ans =
uint16
25396
>> hex2dec('3afb')+hex2dec('2839')
ans =
25396

If there is a possibility that the user might enter hex values with more than 53 significant bits then you should use sscanf with %lx format instead of hex2dec.
