Let's assume the following setup:
I am using frame based processing in Simulink and I have fixed size frames of [1000x1] double.
Let's call this signal s.
Question : How can I produce a Simulink block, b, that removes all samples from s that do not satisfy a given predicate, say -1<x<1, where x is the sample value?
So, for example if I feed
[0.5 -0.2 2 2 2 2 2 ...] to b
then I would get [0.5 -0.2] because all the other samples do not satisfy the predicate -1<x<1.
Summary: I would like to create a filter operation in Simulink just like in functional languages like Haskell, Scala, ML, etc.
Is there a Simulink block like that already?
Or do I have to write my own ?
