I'm looking for a block in Simulink that let me start processing values after X number of samples.

I.E. I got a simulation running, and on a certain input port I don't want that the first 50 samples will be processed but, I want to start to process the sample from the 51. Is there a block that does that?

Hi,

Please check the model layout below:

The "Counter" subsystem counts the number of iterations, then I have used an if-else-then block to trigger the desired subsytem (which is inside an If - action subsytem) only when the iterations exceed 50. I hope this helps.
