# 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. [9 2 -3] - 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.

[9   sqrt(2)   -3]

#### Solution

Let A = [9   sqrt(2)   -3]

As matrix A has only one row.
∴ A is a row matrix.
