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 = [ ...

1 1 0 0 0
1 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 =
