Well, the point of 'eps' is that it is the smallest normalized number so 
it masks the simple roundoff errors. In this case you haven't 
accumulated enough of roundoff to exceed eps, but if you keep going you 
eventually will. A quick try shows that you need four orders of 
magnitude more operations:

min([-1:0.00001:1;]-0.00001*[-100000:1:100000;]<eps)

Sergei showed you the correct form that will never fail.
