Write the order of each of the following matrices:
i. $E=\left[\begin{array}{c}-2 \\ 3 \\ 0\end{array}\right]$
ii, $F=[6]$

Solution:

i. $E=\left[\begin{array}{c}-2 \\ 3 \\ 0\end{array}\right]$
Order of matrix $=$ Number of rows $x$ Number of columns
$\begin{array}{l}
=(3 \times 1) \\
\text { ii, } F=[6]
\end{array}$
Order of matrix $=$ Number of rows $x$ Number of columns
$=(1 \times 1)$
