looking for logical operator

Here's a problem that is surprisingly hard for me to solve and I'm sure there must be an elegant solution: if any of the colums in the follow matrix a_mat contains exactly one logical 1, output 1, otherwise output 0.

a_mat=[0 1 1 0; ...
       1 0 1 0; ...
       0 1 0 0];

solution:

sol_mat=[1 0 0 0];

Is there an 'easy' way to solve this problem using binary operators including xor etc? I used setxor() for previous, similar problems, however cannot get it to work with only one input-argument.

You can do it using sum:

sol_mat = sum(a_mat, 1) == 1

It's working fast enough in matlab.
