Hello,

I know when I log multiple signals from a Simulink simulation and stored the Simulink.SimulationOutput object in the variable "out", I can select a specific signal by writing

elements = out.logsout{1}.Values;

But is there also a way of using the name of the signal instead of the index? (I use Matlab 2022b.)

Then it would not be necessary to first check which index was assigned to which variable.

Just to clarify, when I open the logsout of the Simulink.SimulationOutput instance, in the highlighted column are the names I mean:

Thanks in advance for all helpful answers!

You can use the find method to do so, here is the documentation for the same: Simulink.SimulationOutput.find.

Thank you vrey much for your help! :)

But are you sure? Because in the documentation of the find method it still says

and the name given to the find method isthen "a level higher", so the 'logsout' and not the specific signal name... or what would I need to write to get a specific signal?
