# Column Matrix

## Column Matrix

Matrix with m lines and 1 column.

### Example

This is a column matrix with 3 rows and 1 column: A = $$\begin{pmatrix}1\\3\\–3\end{pmatrix}$$.

• VThis is a 3 × 3 matrix: B = $$\begin{pmatrix}1 & 7 & 9\\3 & –5 & –7\\–3 &4 & 2\end{pmatrix}$$.
• The three column matrices of B are 3 × 1 matrices: $$\begin{pmatrix}1\\3\\–3\end{pmatrix}$$, $$\begin{pmatrix}7\\–5\\4\end{pmatrix}$$ and $$\begin{pmatrix}9\\–7\\2\end{pmatrix}$$.
