See my attached demo to fit a decay curve. Put in the points you see on the graph to train it. For example (0.5, 8) and (5, 1).

Then, simply use rand() to add random noise to the y vector, and possibly also the x vector (if you want).

Thanks a lot for your reply, but my data is not noise. It is supposed to be an earthquake. the figure I shared is the output response of a specified earthquake.

Oh, I thought you were trying to create a simulation (you did mention simulation in your first post). If you have actual data, then simply use plot() to plot your existing data.

I see thanks for your reply.
