Expert Solution
Step 1

A system of m×n numbers arranged in the form of a rectangular array having m rows and n columns is called a matrix of order m×n.

Horizontal lines are called rows and vertical lines are called columns.

An m×n matrix for which m=n (The number of rows is equal to the number of columns) is called a square matrix.

It is also called an n-rowed square matrix. The elements aij | i=j a11, a22, a33, ··· are called the diagonal elements and the line along which they lie is called principal diagonal.
