# Classify each of the following matrices as a row, a column, a square, a diagonal, a scalar, a unit, an upper traingular, a lower triangular matrix. [3000500013] - Mathematics and Statistics

Sum

Classify each of the following matrices as a row, a column, a square, a diagonal, a scalar, a unit, an upper traingular, a lower triangular matrix.

[(3, 0, 0),(0, 5, 0),(0, 0, 1/3)]

#### Solution

Let A = [(3, 0, 0),(0, 5, 0),(0, 0, 1/3)]

As matrix A has all its non-diagonal elements zero.
∴ A is a diagonal martix.
