Oh, yes, I know. And I try to avoid using lambda notation whenever
possible, because I don't fully understand it even when I do use it,
and my students certainly don't. Hence this post.
Again, my point was that I inputted a real-valued function to plot3d,
and a complex-valued one to complex_plot, and both died. But I don't
know how to fix it, unless the code for fast_callable is easier to
work with than I think. Sorry it seems there is no easy fix for this.
