Question

Hello everybody,

I have a variable x that has its value changed every simulation step. What I would like to do is saving each value that x takes in a vector State.

State = [x1 x2 x3 ... xn] with x1, x2, x3, ... xn the values of x at the first, second, third...nth simulation step.

Is it possible ? Is there a block that can do that or do I have to create my own function ?

Thank you very much for your help.

There are multiple solutions for this, dependent on what you want to do with the data.

To save the data to the workspace you can use the'To Workspace' block.

To use the last n values in your model you can for example use the 'Tapped Delay' block.

I needed to save the values during simulation so I used the 'Tapped Delay' block. Thank you very much for your answer !
