Hi all,

I'd like to know how to store the clock value of simulink. In fact, I'd like to do something like that:

if clock=time1+alpha
out3 = true
out4 = false
end

when the clock value is equal to time1+alpha (alpha is a short time) then my outputs (from the embedded matlab function) turn true for o3 and true for o4. However, it doesn't work

thanks

Are you having trouble determining the simulation time? If so, look at the
Clock or Digital Clock sources:

not exactly, actually I'm using a PWM control and when I have an intersection of the reference and the carrier then I'm storing this time. However, when the clock is equal to this time+alpha then I have the conditions for my outputs. I'm using an Embedded Matlab Function where the clock in an input. However, there is only the condition " clock is equal to this time+alpha " that doesn't work.

no ideas ?

another way of explaining what I'd like to get is:
how can I make a condition concerning the simulation time,
for example, if:
clock = previous value of clock + short-time then I have the conditions for my outputs.
I've tried to sotre the value of the clock into the workspace blocks but it doesnt work and I don't know why. :(
