How to Converting sine wave to a square wave in stateflow without invoking simulink function?

i tried using the formula square(t) = sgn(sin(2πt)), but it how can the time period calculated by stateflow. and if we invoke simulink fn what has to be done?

thanks in advance

What do you mean by time period, Sample time OR current simulation time ?

[Azzi Abdelmalek]

Do you want to generate a square wave, or to transform a sine wave to a square wave. If it's a second option, where did the sine wave come from? from Simulink? or generated in Stateflow?

[lakshmi Krishnan]

transform sine wave to a square wave, sine wave is an input from simulink. time period that i mentioned is the sample time.

Even though it is not clear what you want to do, I have attached image to describe how you can work with Simulink function.

If you need a time value, in your Simulink model, add a clock block from Simulink/Sources and connect it as an input to your Stateflow chart
