Chapter 4: Q45. (page 166)

State the dimensions of each matrix.
45. $[\begin{matrix} 2 & 0 & 3 & 0 \end{matrix}]$

Short Answer

Expert verified

The dimension of the matrix is $1 \times 4$ .

Step by step solution

- Define the dimension of the matrix

A matrix A with m rows and n columns is a matrix of dimensions $m \times n$ .

- State an example

Let us consider a matrix $A = [\begin{matrix} 1 & 2 & - 3 \\ 0 & 1 & 4 \end{matrix}]$ . Clearly, matrix A has 2 rows and 3 columns, therefore, the dimension of matrix A will be $2 \times 3$ .

- State the dimension of 2030

In order to state the dimension of the matrix $[\begin{matrix} 2 & 0 & 3 & 0 \end{matrix}]$ , observe that the matrix has 1 row and 4 columns, therefore, the dimension of matrix will be $1 \times 4$ .
