Matrices A matrix, also referred to as a general matrix, is an m by n ordered collection of numbers.
Matrices can contain either real or complex numbers.
A becomes column i of the transposed matrix. The transpose of A is denoted by A T . Each element a ij in A becomes element a ji in A T . If A is an m by n matrix, then A T is an n by m matrix. No movement of data is necessary in your application program when you are processing transposed matrices.
