Posted by Steve Eddins,

"Terminology and notation" - is there a more boring way to start a topic? Unfortunately it's necessary, because there is a lot of variation in terms and equations from book to book and paper to paper. Some of the "frequently-asked questions" arise from simple confusion over notations and conventions. Even... read more >>

Spatial transformations 10
