Using MATLAB packages in Simulink using S-function

Hi!

I am trying to use a MATLAB package that I downloaded from the MathWorks website as part of my Simulink Model. Is there a way to do this? Can it be done using S-functions?

For reference, this is the package: High Precision Orbit Propagator - File Exchange - MATLAB Central (mathworks.com)

Please let me know. Thanks!

Hi Suraj,

I understand that you are trying to use a MATLAB package in Simulink that you have downloaded.

You can use S-functions for the same. If the package you downloaded is in a form that can be compiled into a shared library (DLL or MEX file), you can create an S-Function that calls functions from this library. This gives you more flexibility to integrate external code into your Simulink model.

Here is an overview of how you can use an S-Function to incorporate functionality from an external package:

1. Compile the package into a shared library (DLL or MEX file) if it's not already in this format.
2. Create an S-Function in Simulink and write the interface code within the S-Function to call functions from the shared library. You can use the 'mex' command in MATLAB to compile the S-Function.
3. Use the S-Function block in your Simulink model, and connect it as needed.

Thank you,
