How to stop integration by ODE after the first time step?

Hi,

Does anyone know how to stop the integration by ode45 after the very first time step?

I tried using the odeset and events functions, egs:

function [value,isterminal,direction] = events1(t,T))

but when I got to the step where I needed to define 'value' in the events function, I got stuck. I wanted to use this to stop the integration (by setting isTerminal to 1) on the condition that T is positive, but the parameter 'value' does not seem to allow me to set it that way.

Please advise.

Thanks

Pleae explain, why you think that it "does not seem to allow me to set it that way".
