I have looked for the Lascaux Software package f(z) that Needham references...but cannot find either it or the company Lascaux Software anywhere. Does anyone know if it still available?

I bought a copy a good few years ago. XP was the last version of Windows that it worked on. I have kept an old PC with XP installed so that I can still use it occasionally.
I find I can do a lot with Desmos which is free. Search for it and try it. It doesn't have specific facilities for handling complex numbers but I have managed to project the complex potential onto the Riemann sphere as in chapter 12.

Vasco In these parts the free R computer notation seems to be most popular among scientists who plot a lot of graphs. I think it works on just about every operating system.

Thanks for the above info. The link is to a university library catalogue. As you say f(z) only works on XP, I'll abandon my search. Thanks for the pointer to R, I'll have a look at that. I have looked at Sage Math and Mathematica...but cannot quite justify the cost of the latter.

Here is a link to a page that discusses the complex facilities of R.
