> Vectors and matrices are only one way to model linear transformations; They help beginners to imagine linear algebra; But often, refraining from using coordinates delivers a much clearer picture. They also make for a handy model when mapping them in to computer systems. It's hard to know from those quotes how things are actually presented in the material, but an emphasis on matrix & vector view of the world is really not a bad idea that I wish was more prevalent in math education.
