Is it possible to enter directly the hexadecimal number without the conversion to decimal number and perform all the hexadecimal operation like AND,OR, XOR?
For example a = 0x53656174 , b = 0x454B5350
c = bitand(a,b)
how to represent the hexadecimal number in matlab?

Unfortunately, there is no support for hexadecimal literals. The best you can do is:
a = hex2dec('3656174');
b = hex2dec('454B5350');
However, there is support for displaying in hexadecimal:
format hex
c = bitand(a, b)

Hi @Guillaume,
Thanks for your tips.
BTW, how about the floating point format such as single (float32), double (float64), or CustomFloat?

Ran in:
Since R2019b it is possible to directly enter literal hexadecimal and binary numeric values:

0x2A
ans = uint8 42
0b101010
ans = uint8 42
