Evaluate an Interpolating function and export results as a table?

Hello, this is a ridiculously simple question but I have been working on this far too long and I'm getting no where.

I would like to produce a table of output values based on an interpolating function. The interpolating function is a solution to a nonlinear differential equation and I am able to plot the solution. Frustratingly, I am not able to evaluate the function at specific points or make a table of output values. Ultimately, I'd like to export a table of values say at points t=0 to t=10 that I can import into Excel.

Thank you!! Scott Vaughen

Perhaps you can adapt this

sol=v[t]/.NDSolve[DE,v[t],{t,0,10}][[1]];
points=Table[{t,sol},{t,0,10,1}];
Export["file.csv",points]

Thank you!!! Thank you!!! Yes, I am making some progress with this!!

I can eventually turn this into a lesson for my class!

I wasn't able to retrieve the .csv file, I just got the output line "file.csv".... but I couldn't find the file, maybe it's because I'm currently using the free version of the wolfram programming lab.

But I was able to actually see all the results of my interpolating function evaluated at a series of input values for t=0 to t=10. That was my main goal. At this point, I'm just typing the data into excel based on what I can read from the output.

THANK YOU THANK YOU for the quick reply!!!
