Terminating some Simulink samples
显示 更早的评论
I have a serial stream of samples in my Simulink model and I would like to be able to "terminate" the first N samples. Is there a way to do that?

this is how I would do it:
I would put a clock block (in Simulink sources library) and connect it to a "compare to constant" block (in Simulink logic and bit operations library).
This way you can compare the time with any number you choose and you will get a 0 or 1 out of the compare to constant block. Knowing what is your smpling time, you can conver, comparing the clock (time) with a constant to comparing the sample number with a constant just by dividing time out of clock with sampling time which can be found in the "Weighted Sample Time" block (in simulink Signal attributes library)

"Switch" block?

It depends on what blocks your model includes.
For example you can multiply that 0/1 signal with any signal you want like signals coming out of a source block. This way the source result will be zero for specific sampling times.
Or you can use a switch block as Ilham mentioned. This way you can feed the 0/1 signal to the middle inport signal of the switch block and put your other signals on the other inports of that.
