# 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. [3-2400-5000] - 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, -2, 4),(0, 0, -5),(0, 0, 0)]

#### Solution

Let A = [(3, -2, 4),(0, 0, -5),(0, 0, 0)]

As every element below the diagonal is zero in matrix A.
∴ A is an upper triangular matrix.
