The elements of a matrix A are noted by Aij or aij. A matrix with m=n is a square matrix. If two matrices A and B have the same number of rows and columns and all of the elements Aij = Bij, then A = B. Definition: The transpose of a m(n matrix A = [Aij], denoted AT, is AT = [Aji]. A matrix is symmetric if A = AT and skew symmetric if A = -AT. ................
