This article is about GeoGebra command.

##### Command Categories (All commands)

Element[List, Number n]
Yields the nth element of the list.
Example:
`Element[{1, 3, 2}, 2]` gives 3, the second element of {1, 3, 2}.
Element[Matrix, Row, Column]
Yields the element of the matrix in the given row and column.
Example:
`Element[{{1, 3, 2}, {0, 3, -2}}, 2, 3]` gives -2, the third element of the second row of {{1, 3, 2}, {0, 3, -2}}.
Element[List L, Index1, Index2, ...]
Provided L is n-dimensional list, one can specify up to n indices to obtain an element (or list of elements) at given coordinates.
Example:
Let L={{{1,2},{3,4}},{{5,6},{7,8}}}. Then `Element[L,1,2,1]` returns 3, `Element[L,2,2]` returns {7, 8}.
Note: For this command to work, the list or matrix can contain elements of one object type only (e. g., only numbers or only points.

## CAS Syntax

Element[List, Number n]

Element[Matrix, Row, Column]
Yields the element of the matrix in the given row and column.
Example:
`Element[{{1, 3, 2}, {0, 3, -2}}, 2, 3]` gives -2, the third element of the second row of {{1, 3, 2}, {0, 3, -2}}.
