Taking common from matrix
WebData common to A and B, returned as a vector, matrix, or table. If the inputs A and B are tables or timetables, then the order of the variables in C is the same as the order of the variables in A. The following describes the shape of C when the inputs are vectors or ... Web2 Common vector derivatives You should know these by heart. They are presented alongside similar-looking scalar derivatives to help memory. This doesn’t mean matrix derivatives always look just like scalar ones. In these examples, b is a constant scalar, and B is a constant matrix. Scalar derivative Vector derivative f(x) ! df dx f(x) ! df dx ...
