Commutative Law of Addition of Matrix: Matrix multiplication is commutative. This says that, if A and B are matrices of the same order such that A + B is defined then A + B = B + A. Proof: Let A = [a ij] m × n and B = [b ij] m × n. In this section we'll explore how the eigenvalues and eigenvectors of a matrix relate to other properties of that matrix. This section is essentially a hodgepodge of interesting facts about eigenvalues; the goal here is not to memorize various facts about matrix algebra, but to again be amazed at the many connections between mathematical concepts.The first is the determinant of a product of matrices. Theorem 3.2.5: Determinant of a Product. Let A and B be two n × n matrices. Then det (AB) = det (A) det (B) In order to find the determinant of a product of matrices, we can simply take the product of the determinants.
