Export to matrix?

I was wondering if it was possible to export a STAN model as a matrix (e.g. as a CSV file).
Thanks.

To export all the information contained in your model as csv files, select Edit > Data Explorer and click the Export button.

Thank you. I have unfortunately not been lucky in generating what I am looking for.

I would like to generate a matrix where columns represent processes and rows represent goods, and matrix elements represent flows.

This type of matrix is used in e.g. life cycle assessment.

Could you post a simple MFA example with the corresponding desired matrix?

Something along these lines (see attached).

Sorry, there is no way to create such matrices automatically with STAN.
