i have a set of values for the force term "F" (in the equation my"+cy'+ky=F) saved in an excel file which i have recalled using:
My main code looks something like:
whereas, my function code looks something like:
The problem is that i want to recall each value of F at different time steps but i dont know how to do that, can anyone guide me?
Note: F here is not time dependent rather it has been taken from results obtained from a simulation software. Then what should be my approach?
