MATLAB: Changing Matrix value at odd position of row with reference to a certain column

MATLABmatrix arraymatrix manipulation

I was just wondering is there any elegant solution to make those '1 0 0 0 0' become ' 0 0 0 0 0' and '1 1 1 0 0' become '1 0 0 0 0'?
I might need to consider N number of matrices so a general solution instead of fixed solution will be helpful. Thanks.

or
B = zeros(size(A));
B(:,1) = sum(A,2) > 1;
