This section discusses the similarities and differences between notational conventions that are used in the various fields that take advantage of matrix calculus. Although there are largely two consistent conventions, some authors find it convenient to mix the two conventions in forms that are discussed below. After this section, equations will be listed in both competing forms separately. WebMuch of the confusion in taking derivatives involving arrays stems from trying to do too many things at once. These \things" include taking derivatives of multiple components …
