how xor is used between two no.? or which command ?

LL=mod(176+233,256) xor (142);

Answer 1

I suspect that you actually want to be using bitxor (and possibly also specify the classes):

>> bitxor(mod(176+233,256),142)
ans =  23

Note that xor, like all logical operators in MATLAB, treats non-zero elements as true, so given that both mod(176+233,256) and 142 are non-zero we already know that the output will be false:

>> xor(mod(176+233,256),142)
ans = 0

xor(mod(176+233,256),142)

Is this what you are looking for? Is so,a quick MATLAB documentation search would have sufficed instead of taking the pain to post question here.
