Hello, Let's say that I'm getting y=[1 5 7 2 3] at Time=[0 1 2 3 4 5] in a Simulink simulation. At Time=6, I would like to use all the previous values stored in y. I tried Unite Delay, Memory, and Data Store Blocks. But they didn't work. I also tried to make a costumized function in matlab, but it works on point-by-point bases. Is there any other way around this?

Thanks in advance

You can use buffer in Simulink to store a specified number of values. The buffer block will output a vector when after receiving the number of samples and you can process on the past values.
