- Element[List, Number n]
- Yields the nth element of the list.
- Element[Matrix, Row, Column]
- Yields the element of the matrix in the given row and column.
- 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.
