Alternative solution for NAN

The following code gives NAN (Not a Number) values
[U,D]=eig(N);

To solve this problem, I wrote that
while(det(N) == 0)
N=(1e-10.*randi(1,size(N)))*eye(size(N));
end

But, the loop does not stop :( Are there any alternative solution instead of this loop to solve the NAN problem ?
