request for algorithms

[Rick Coates]

I would like to know if anyone here in net land has implemented some
algorithms (in C, of course):
	
	1. Zeros of real and complex polynomials: algorithms 419 & 493
	   from "Collected Algorithms from CACM" (or even the original 
	   Fortran as given)

	2. Hidden line plotting routine: algorithm 420 ibid

	3. The psychrometric chart as described by ASHRAE standards
	   (American Society of Heating, Refrigeration, and Air conditioning
	   Engineers ) - even an algorthm that accurately describes the
	   chart at any barometric pressure would be helpful

Well, I hope that is a diverse enough list; also, any other algorithms and
implementations might be interesting ... net.sources is pretty slow.
