Take a look at Dusko Savic's"Object Oriented Programming in Smalltalk/V"
New York: Ellis Horwood, 1990. ISBN 0-13-040692-9.

There is a 50 page chapter on using Smalltalk/V for numerical mathematics,
with lots of sample code. It includes methods for statistics, and code to
solve various classes of differential equations.

The chapter on graphics begins with a discussion of matrices, and goes on
to provide code for manipulating both 2D and 3D matrices. The application
examples are for doing things like rotating objects in 3D space. 

I just bought this book, so I can't comment on how it feels to try and
use it as a guide to learning. But there certainly is a lot of code. 
I'd like to know if there is a way to obtain it electronically. I'll
surely suffer from carpal tunnel syndrome if I type all this stuff in.
