For example X = [[1, 2], [4, 5], [3, 6]] would represent a 3x2 matrix. If A = [a ij] be an m × n matrix, then the matrix obtained by interchanging the rows and columns of A would be the transpose of A. of It is denoted by A′or (A T).In other words, if A = [a ij] mxn,thenA′ = [a ji] nxm.For example, Matrices with a single row are called row vectors, those with a single column are called column vectors. A matrix with the same number of rows and columns is called a square matrix. If m = n, the matrix is called a square matrix of order n. A square matrix in which only the diagonal elements α = α ii are nonzero is called a diagonal matrix and is denoted by diag (α 1, …, α n). Here is a matrix and its transpose: The superscript "T" means "transpose". 2.
