How to Delay matlab function block?

Hello everyone,

I have a system that is shown below.

Inside the Sensor Block I have some initial values and basic calculations like below;

function [distance,sensorID] = fcn(trig)
sensorID = 1;
distance = (trig/2)*(17.15);

with the current structure I can display all the values correctly.However, my aim is to display distances with delays from each other.

For instances I want to display;

Display[Distance] at the beginning

Display[Distance]2 after 3 seconds

Display[Distance]1 after 6 seconds

I have already tried pause function but it makes the function in the block to restart constantly and that is something I avoid. All I need to display values once and after a second turn back to zero,if possible.

If not values can remain on the display,as well.

I hope I could have explained the issue clear enough.Please let me know if there is any other point that I need to clarify.

Thanks in advance!

Have you tried Delay blocks?

Thank you for your answer.

I have tried but not sure if I found out the correct way to use or it basically did not work.

Do you mind if I ask you how would you use the delay block in this case?

Thanks again.

You can place a Delay block before each of the inputs of the second and third sensor blocks. The delay length would depend on your step size. For example:

If your step size is 0.1, and you want a 3s delay, the delay length (in samples) would need to be 30.

Maybe not the most elegant solution but it might be enough for you.

Thank you very much.It works now.
