Hi, I have been working with Simulink just for few days. I have a Discrete State Space system. My input is defined in the "Model Configuration parameter" as [time',i1s',i2s'], where i1s and i2s are my source currents. Let's say that the size of i1s' is equal to N x 1. I get a voltage as an output. Now, the output should be a vector that has a number of rows equal to 2N x 1. I want to extract only the first N rows. Which block shall I use in Simulink? I am taking a look at Selector and Variable Selector but I cannot make them work.

You want to extract those rows to workspace?

I would need to extract the rows because I need to do some operations in Simulink with the first Nx1 components, and other operations with the remaining components

Use a Demux with 2 outputs. It should divide the rows equally.

Hi, I tried and it seems to work! But, I do not really understand how to see the components of the vector in Simulink. I attach the model I have with the data to use in order to simulate it.
