Matrix Vectorization

  • Phoebus J. Dhrymes


It is frequently more convenient to write a matrix in vector form. For lack of a suitable term, we have coined for this operation the phrase “vectorization of a matrix.” For example, if A is a matrix of parameters and à the corresponding matrix of estimators, it is often necessary to consider the distribution of
$$\tilde A - A$$
We have a convention to handle what we wish to mean by the expectation of a random matrix, but there is no convention regarding the “covariance matrix” of a matrix. Similarly, there is a literature regarding aspects of the (limiting) distribution of sequences of vectors, but not for matrices.
