WebIntroduction to Matrices. The trace tr(A) of an n × n matrix A = (aij) is the sum of the diagonal entries of A. That is, tr(A) = ∑ni = 1aii. The transpose AT of an m × n matrix A is the n × m matrix whose (i, j) -entry is aji. We say two matrices A, B commute if AB = BA. The entries aii of a matrix A = (Aij) are called diagonal entries.
