- run the script
- rename Tp
- run the a second time
How can I multiply one output of this function with another output from this function?

I need to be able to multiply the Tp matrix I get out of this script with another Tp matrix I get from this script using different or potentially the same input variables. How can I do this?

Or convert the script to a function that returns Tp and call the function twice. That's more robust.
