How to perform xor operation on an three input binary bits.

for two inputs we use xor(1,0),

for three input bits xor(1,1,0), gives error.

How to perform the calculation?

在 MATLAB Online 中打开

a = xor(1,1); %1 xor 1 = 1
b = xor(a,0)  %1 xor 0 = 0
%or
c = xor(xor(1,1),0)

The MATLAB function xor takes two input arguments and and provides and xor between the elements of each argument.

So for example

x = [true;false;true]
y = [false;false;true]
z = xor(x,y)

z =

There are three separate inputs in my case, these are feedback signals which needs xor operation

Note xor is a binary operation which takes two inputs bits and provides one output bit. The output bit is set to true (1) if exactly one of the input bits is 1 otherwise it is set to zero. I don't understand what you mean by taking the xor of three inputs. Please explain further exactly what operation you are trying to perform. So for example if you have for your three inputs u1 = 1 (true) u2 = 1 (true) u3 = 0 (false) then how do you define your output "xor".
