Exactly! I wanted to plot my real-world u vs t, and then plot several
curves on top of that showing the estimated u for a few selected x.
However, I got to Raymond's message too late, after having found function
uniroot() in GNU R, where I'm doing the rest of my work. It wasn't hard
to create a loop (as you suggested) there that applied uniroot() to those
specific subsets. Next time I'll try doing this all in maxima as I become
more familiar with it.
Thanks to all those who provided some input.
