如何在matlab中將Bitxor表示爲mod

Question

我想一起實現xor。例如，我有兩個比特對，分別是6（110）和3（011）。現在我想實現兩個輸入的按位異或。它可以通過matlab中的bitxor函數來完成。

out=bitxor(6,3);%output is 5 

但我想通過mod函數而不是bitxor實現該方案。如何用matlab做到這一點？非常感謝。這是我的代碼

out=mod(6+3,2^3) %2^3 because Galois field is 8 (3 bits) 

Answer 1

代碼

function out = bitxor_alt(n1,n2) 

max_digits = ceil(log(max(n1,n2)+1)/log(2));%// max digits binary representation 

n1c = dec2bin(n1,max_digits); %// first number as binary in char type 
n2c = dec2bin(n2,max_digits); %// second number as binary in char type 

n1d = n1c-'0'; %// first number as binary in double type 
n2d = n2c-'0'; %// second number as binary in double type 

out = bin2dec(num2str(mod(n1d+n2d,2),'%1d')); %// mod used here 

return;
