Number of directions according to which the data are organized and identifiable in a space with equivalent dimensions.

The elements in a

table are located based on an index composed of the number of elements corresponding to the dimension of the table. The elements on a one-dimensional data table will be identified by an index with one element, which is also called the

rank of the elements in the table. The elements in a two-dimensional data table will be identified by an index formed by

pairs of values.

A number table is sometimes called a matrix. In this case, the dimension of the table corresponds to the matrix size.

### Examples

Here is a 1-dimension table; the first line provides the rank of each element in the table.

Here is a 2-dimension table, formed by two entries: one horizontal entry and one vertical entry.
