search for: 30mv

...t. I need for the event to trigger when init[1] is >= 30. Setting the root to init[1]+30 did not produce the desired result, making it init[1]-30, produced something better but I'm not sure that it is right yet. The actual equations are: v' = 0.04v^2 + 5v + 140 - u + I u- = a(bv-u) If v=30mV then v-, u-u+d Any help would be appreciated.
