Hey all, I writed a tutorial about vectors and matrices a while back now, and so far have gotten good reviews about it. But surely the test is here, people are always able to finds things wrong with anything here, so, for good measure, take a look at it here and tell me what u lot think. Let the slating begin.....

By "Generic Rotation Matrices" do you mean rotation about an arbitary vector? If so I suppose I could add that, although I''d leave out the derivation, as it''d be too long ( the tutorial is large enough as it is ).

As for the planes, yes, I could add them, and I may, but not at the moment, I''m very busy so I don''t have time to add a whole new section. I may put that into a further tutorial though....

Personally I would seperate the vectors from the matrices. I think it would be a bit much for a person new to the concepts in one setting. I also think there are a few problems with the ordering. It is ok for a refresher, but it would be confusing to someone that never had it. As an example you mention unit vectors and directions before you tell them that a vector has a magnitude and direction. You introduce representations of vectors that involve multiplication by scalars and addition of vectors before you introduce those concepts. That makes the statements meaningless. A person either moves on saying they have no idea what you are talking about, abandons the document saying they need a more remedial document or they set there puzzling over what in the world that means.
