WebWe have the following generalizations of the product rule in single variable calculus . In the second formula, the transposed gradient is an n × 1 column vector, is a 1 × n row vector, and their product is an n × n matrix (or more precisely, a dyad ); This may also be considered as the tensor product of two vectors, or of a covector and a vector. WebAlso, the dot, cross, and dyadic products can all be expressed in matrix form. Dyadic expressions may closely resemble the matrix equivalents.
