In this video, I introduced the theory of coordinates, transformation matrices and B-matrices in linear algebra.   This video focuses on presenting the notation I use, which I find it useful to parse in our mind.  This aligns with the concept in computer science that we should name the variables such that it is easy to comprehend, instead of giving it a single letter name.
