I have three groups of number which can be 0 or 1. like A, B and C. I want to write a conditional to be true if 2 of three values were 1. How can I do that?
The simplest way would be like:
if (A==1 && B==1) or (A==1 && C==1) or (B==1 && c==1)
but I am searching for sth shorter.
Any idea?

If the values can be something other than 0 and 1, it is not clear how you want to compare them.
(A~=0) + (B~=0) + (C~=0) >= 2 %non-zeros
nnz([A,B,C]) >= 2 %non-zeros
sum([A,B,C] == SomeValue) >= 2 %match SomeValue specifically
nnz([A,B,C] == SomeValue) >= 2 %match SomeValue specifically
