It acts like the number one for matrix multiplication. A diagonal matrix is a square matrix that has zeros off the main diagonal. Let be and , where and . The transpose of the matrix , written , reverses the rows and columns of , so that is and .Of course, matrix multiplication is in general not commutative, so in these block matrix multiplications, it is important to keep the correct order of the multiplications. When the blocks are square matrices, the set of invertible block matrices is a group isomorphic to the general linear group , where is the ring of square matrices .The trace of an n×n square matrix A is defined to be Tr(A)=sum_(i=1)^na_(ii), (1) i.e., the sum of the diagonal elements. The matrix trace is implemented in the Wolfram Language as Tr[list]. In group theory, traces are known as "group characters." For square matrices A and B, it is true that Tr(A) = Tr(A^(T)) (2) Tr(A+B) = Tr(A)+Tr(B) (3) Tr(alphaA) = alphaTr(A) (4) (Lang 1987, p. 40), where ...Compute answers using Wolfram's breakthrough technology & knowledgebase, relied on by millions of students & professionals.
