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. WebSep 1, 2024 · How to calculate the gradient of a matrix. Ask Question. Asked 3 years, 7 months ago.
