Well, in the order from easy to difficult:
Near the bottom of this page:
http://www.ldraw.org/reference/tutorials/parts/
I've written something about manipuating 3D-Ldraw objects with matrices,
it's the section starting with the line "Manfred Moolhuysen writes:".
I've kept my explanation as "no-math" as possible. Therefore it will
probably not cover all you would like to know about matrices, but it's a start.
Also, If you do a search on Lugnet with the keyword "matrices" you will
fond some treads that go deeper into the subject, for instance:
http://news.lugnet.com/cad/mlcad/?n=1131
If your looking for hard boiled mathematics an formulas on the subject,
please look here:

Greetings, M. Moolhuysen.
