How to stop ode integration?

I'm trying to solve a differential equations system with ode45 solver. But sometimes integration takes too much time because one of three values in the system becomes too small. As I understood I should use an event in ode function.

 function [value,isterminal,direction] = events(t,y)
 value = y(1) - 0.0000001; 
 isterminal = 1;
 direction = 0;

How to write the event not just only for one y value, but for all three of them?

function [value,isterminal,direction] = events(t,y)
  miny = [0.0000001, 0.000000025, -83.9];   %for example
  value = y < miny; 
  isterminal = 1;
  direction = 0;

Thank you.

Ah, it should probably be

isterminal = ones(size(y));
direction = zeros(size(y));
