Column Matrix: Row Presentation
When presenting a column matrix on the printed page, the decision is often made to save space by presenting it horizontally instead of vertically.

However, it is not then straightforward to recognise that a column matrix, and not a row matrix, is meant.

Hence, in order to alleviate the confusion, braces are often used as delimiters for such a presentation.

Thus the column matrix $\mathbf C$ above would then be presented as:


 * $\mathbf C = \set {\begin {matrix} c_{1 1} &c_{2 1} & \cdots & c_{m 1} \end {matrix} }$
