Definition:Column Matrix

Definition
A column matrix is an $m \times 1$ matrix:


 * $\mathbf C = \begin{bmatrix}

c_{1 1} \\ c_{2 1} \\ \vdots \\ c_{m 1} \end{bmatrix}$

That is, it is a matrix with only one column.

If such a matrix is an element of a vector space, it is also called a column vector.
