If n = p, then the order of the matrix 7X – 5Z is:
(A) p × 2
(B) 2 × n
(C) n × 3
(D) p × n
3 5 Transpose of a Matrix
In this section, we shall learn about transpose of a matrix and special types of matrices
such as symmetric and skew symmetric matrices Definition 3  If A = [aij] be an m × n matrix, then the matrix obtained by interchanging
the rows and columns of A is called the transpose of A
