Derivative wrt matrix
Webwhere F ′ ( A ( t)) is a rank-4 tensor which encodes the derivative of F and a, b, c, and d are indices of the above matrices and tensors. For example, if F ( A) = A − 1, then F ′ ( A ( t)) a b; c d = − ( A ( t) − 1) a c ( A ( t) − 1) d b which reproduces the expression for d d t A ( t) − 1 given in the question.

Matrix calculus refers to a number of different notations that use matrices and vectors to collect the derivative of each component of the dependent variable with respect to each component of the independent variable. In general, the independent variable can be a scalar, a vector, or a matrix while the dependent variable can be any of these as well. Each different situation will lead to a different set of rules, or a separate calculus, using the broader sense of the term.
