format long g
T = readtable('hex codes example.xlsx')
T.DecCodes = hex2dec(strrep(T.HexCodes,' ',''))
writetable(T,'hex and dec codes example.xlsx')

Do you mean you have the hex representation of a double precision number and want to convert it into the corresponding double? See the num2hex and hex2num functions.
Or are you trying to convert integer values? In that case see the dec2hex and hex2dec functions.

hex2num() can only handle double precision . You need other approaches for single precision.
But they are unlikely to be single precision or double precision.
format long g
H2=[0xfa 0x80 0x3e 0x11 01 04 00 00]
typecast(H2, 'double')
swapbytes(ans)
typecast(H2, 'single')
swapbytes(ans)
