Add two binary matrices and get only "1" in each row

Hello eveyone!

I have two binary matrices(m*n),i want to add those two matrices but in order to get only '1' in each row .

this is the output matrix ,for example in row (2,5,6 and 7) i have two '1' ,there is any solution to eliminate one of them ?

0 0 0 0 0

0 0 1 1 0

0 0 0 1 0

0 0 0 0 0

0 0 1 0 1

0 1 0 0 1

1 1 0 0 0

1 0 0 0 0

0 0 0 0 0

0 0 0 0 0

Would you please help me ?

For the case (like rows 2 and 7) where the binary/logical matrices have 1's in different columns, which of the two 1's do you want to keep?

And are your matrices of class logical? Or class double? Or some integer class? It makes a difference!!!

This is one way

M = [ ...
     0     0     0     0     0
     0     0     1     1     0
     0     0     0     1     0
     0     0     0     0     0
     0     0     1     0     1
     0     1     0     0     1
     1     1     0     0     0
     1     0     0     0     0
     0     0     0     0     0
     0     0     0     0     0];
 
 M_out = M*0;
 [v, c] = max(M, [], 2);
 idx = sub2ind(size(M), find(v), c(v==1));
 M_out(idx) = 1;

Result

 >> M_out
M_out =
     0     0     0     0     0
     0     0     1     0     0
     0     0     0     1     0
     0     0     0     0     0
     0     0     1     0     0
     0     1     0     0     0
     1     0     0     0     0
     1     0     0     0     0
     0     0     0     0     0
     0     0     0     0     0
