How to save the time of the simulink simulation on matlab?

Hello,

I need to create an "if" block on simulink, the block must be triggered when the simulation time is =0. My idea was to save the simulation time of simulink on a matlab variable and then to use it on simulink in a constant block.

Someone knows how to do that?

hello

I have some difficulty to understand what your intention is

what is the reason to trigger (once ?) at t= 0 ?

or do you want to save a "hit" time when the trigger condition occurs ?

Use the Clock block in your Simulink model. It outputs the simulation time. Do whatever you want.
