The Transformation Matrices of vec A to vec A^T for Diagonal Matrix

Rusdi Ahmad, Yanita Yanita, Lyra Yulianti


This study aims to discusses the transformation matrices of vec A to vec A^T for diagonal matrix. The matrix used is a 4 x 4 diagonal matrix assuming that two pairs of elements are located on the main diagonal with the same value. To get the transformation matrices, this uses the commutation matrix equation is  K_mn  vec(A)=vec(A^T ). Therefore, several K_mn commutation matrices are obtained on a 4 x 4 diagonal matrix.
