WebThese “matrix transformations” are an important tool in geometry and, in turn, the geometry provides a “picture” of the matrices. Furthermore, matrix algebra has many other applications, some of which will be explored in this chapter. This subject is quite old and was first studied systematically in 1858 by Arthur Cayley.
