There are 3 rows and 1 column. We write the number of rows first. The rows are laid out horizontally while the columns are vertical. We say this is a "3 by 1 matrix".
For this case we have that by definition, the dimension of a matrix is given by:
The number of rows by the number of columns
It is observed that we have a column that consists of three rows.
