i am trying to declare one qudratic equation but getting this error in R2017b and R2020b also
M1=bit3xor(u2,w2,bitxor(bit3xor(bitand(v2,d2))));
Error: Undefined function or variable 'bit3xor'.
Please someone help me in removing this error.

There is no such "bit3xor" inbuilt function in MATLAB. It might be custom function, if so please keep the bit3xor.m file in the same working directory.

Thank You Sir.
But Sir I made change and used like this for f10 equation but still operation is not working What is going wrong in this.
f10 = 1 + v2 + x2 + x2v2 + x2v3 + x3v2 + x2w2 + x2w3 + x3w2
This qudratic equation I want to evaluate using Matlab so I wrote like this.
Z=quad(0,1,1,0,1,0,1,1);
function F10 = quad(u2,v2,w2,x2,u3,v3,w3,x3)
F10=bitxor(1,v2,x2,bitxor(bitxor(bitand(x2,v2),bitand(x2,v3),bitand(x3,v2)),bitxor(bitand(x2,w2),bitand(x2,w3),bitand(x3,w2))));
end
