### What is Meant by Diagonal Matrix?

In maths, matrix is an arrangement of items or elements in rows and columns. A diagonal matrix is a square matrix in which all the elements are equal to 0 except the principal diagonal elements. A square matrix D = [dij]n x n is called a diagonal matrix if dij = 0, whenever i ≠ j. This matrix also possess some properties with respect to addition, multiplication, transpose and inverse. The best example of this of type of matrix is identity matrix.
