Details:

According to the Matlab documentation, the first input of dec2hex can be a
character array:
https://www.mathworks.com/help/matlab/ref/dec2hex.html#mw_7e982b61-105a-4d38-9301-a9f469b05bce
and it will be converted as integers.


>> dec2hex('.')
ans =
    '2E'


I would change the input conversion in dec2base.m:


if (islogical (d) || ischar (d))
    d = double (d);


but the documentation mentions "dec2hex treats characters as their Unicode".
