In this chapter the focus is on the basic features of such transformation processes themselves, with minimal regard to the notion of solving specific problems. The focus is on understanding procedures for casting and potentially reorganizing a linear transformation into a form that is convenient for addressing whatever problem is at hand. In this process, it becomes important not only to treat the linear transformation when it is expressed within a particular basis, but also to recognize when it is in fact more useful to treat it in a way that is independent of basis. For this purpose, certain notational distinctions are introduced on page. Once these concepts are in place, the issue of solving specific problems of
