Hello I have a hex cell array and I indexed them.
For example I have 'A7' and when I use hex2dec, it gives me nonsense result which is -7.7452e-121. how can I get exact result? I mean I want to see that hex A7 = decimal 167.
Thank you.

hex2dec('A7') % what you should have used
hex2num('A7') % what you actually used
The unfortunately named NUM2HEX and HEX2NUM convert to/from the IEEE 754 floating point hexadecimal representation, they are completely unsuitable for your task. Just for interest, the complete hexadecimal is:
num2hex(hex2num('A7'))
Apparently someone thought that it would be a good idea to pad its input with trailing zeros. Ugh.
