So  [FI] in attached is my forcing function data, which occurs from 0-26.88 seconds at 0.01second interval. I tried to assign [FI] in the procedure a couple ways with no luck. Is it possible to assign F as this list of values?

I have no experience with writing code and procedures in software and this is a little outside of the scope of the grad course I am taking (no pre-requisite requirements in coding software). So im certianly appreciative of the help. Also you will have to excuse my ignorance as this stuff is a different language to me.

So say if I had the forcing funtion [F] defined would I store that matrix in the code said here? Im hoping I can just import the F list in from my excel file and store as r:=. The time step is 0.01 seconds so goes from 0s to 26.88s in 0.01s intervals. Would i need to define the time as a matrix as well?
