test_ball.m

Hi,

I want to know how I can change the value of a vector during the integration. For instance, every 5 minutes, add 3 to y(2)...

I found a solution for t==t1 : use events in the ode options (see the file test_ball.m the name comes from ballode.m) but if I want to do the same for 5, 10, 15 etc it doesn't work... I changed value = t -5 in mod(t,5) and in (t>0 && mod(t,5)==0)-1 without success.

Thanks and sorry for the mistakes.
