I have
plain_tex = ('1111110000011111001111011110100010100110110111000110011010110')
this string I want to convert to that form
plaintext_hex = {'39' '8a' '59' 'b4' 'ac' '00' '00' '00' ...
'00' '00' '00' '00' '00' '00' '00' '00'};
%plaintext_hex = {'398a59b4ac000000000000000000000'};
%str=num2hex(plaintext_hex)
%plaintext_hex = {'32' '43' 'f6' 'a8' '88' '5a' '30' '8d' ...
% '31' '31' '98' 'a2' 'e0' '37' '07' '34'};
or directly dec as I will then do that Convert plaintext from hexadecimal (string) to decimal representation
plaintext = hex2dec(plaintext_hex)

'00' '00' '00' '00' '00' '00' '00' '00'};
this is 1* 16 cell , ot is hexa.string
plain_tex = ('1111110000011111001111011110100010100110110111000110011010110')
this is 1*32 char. it is binary
