I didn't know about blitz++, but I've just now taken a quick look at it. It 
appears designed for performance above all, which is not the idea behind my 
equation toolkit. The equation toolkit is designed to let you *easily* write 
straight-forward equations, combine them, and re-assign them as you want. 
For instance:

=================
Equation e = x + y
print e(x -> 1, y -> 2)
e = y
print e(y -> 9)
e = z + 2 * y / a + b
print e(a -> 2, b -> 5, y -> 100, z -> 50)
=================

The advantage is that you can easily change an equation so you don't 
actually have to write functions for each equation. If you have a situation 
where you need to dynamically change around equations a lot during runtime, 
this system should (ideally) be useful.
