Transpose of matrices
Definition (Transpose of matrices)
Let A be any matrix. The Matrix obtained by interchanging
rows and columns of A is called transpose of A and is
denoted by A or At or AT
Thus if A = [aij ]m×n, then A = [aji ]n×m

Properties of Transpose of Matrices
Property
1 (A ) = A, for any matrix A
2 (A + B) = A + B , where A and B are matrices of
same order
3 (AB) = B A provided AB is defined
4 (kA) = kA , where A is any matrix and k a scalar

Theorems on Transpose of Matrices
Theorem (1)
For any square matrix A, A + A is symmetric and A − A is
skew-symmetric matrix
Theorem (2)
Every square matrix can be uniquely expressed as sum of
symmetric and skew-symmetric matrix
Theorem (3)
All diagonal entries of skew-symmetric matrix are zero.
