A friend and I have made a functon that taking the simulation output results (out) and a struct specifying certain parameters (plot_format) as inputs would return the simulation results plotted in the format specified by the aforementioned struct plot_format.

The issue is with "out", which comes in a SimulationOutput format, when we would need it in a struct or cell fomat, in order for the function to be able to work with it.

How could we do it?

The contents of a Simulink.SimulationOutput object can be accessed with dot indexing very similar to a struct, so it's not clear to me how converting it to a struct would help. Can you show a very abbreviated version of your function so we an see what you're trying to do?

Hi Antonio,

To address the issue of converting simulation output data from the SimulationOutput format to a struct or cell format, which is necessary for your function to process the simulation results, you can leverage the "Data Import/Export" settings in the "Configuration Parameters" of your Simulink model. The following are the steps to Configure Data Import/Export Settings:

Open Model Configuration Parameters: Open the model in Simulink. Then, navigating to the model's Simulation menu, select "Model Configuration Parameters" or click on the gear icon.
Navigate to Data Import/Export: In the Configuration Parameters window, the "Data Import/Export" section on the left side should be located.
Configure Output Save Format: Under the Data Import/Export settings, the option labeled "Format" is found. There, the format in which the simulation output data is to be saved can be selected. The options include "array", "structure", "structure with time", "dataset".
Apply and Save: Select the preferred format and click "OK" or "Apply" to save the changes.
Run Simulation: Execute the simulation with the set configuration. The output will be in the chosen format, ready for use with the function.
