Element[ <List>, <Position of Element n> ]
Yields the nth element of the list.
Example:
Element[{1, 3, 2}, 2] yields 3, the second element of {1, 3, 2}.
Note: In the Menu view cas.svg CAS View undefined variables can be used as well.
Example:
Element[{a, b, c}, 2] yields b, the second element of {a, b, c}.
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] yields -2, the third element of the second row of \mathrm{\mathsf{ \begin{pmatrix}1&3&2\\0&3&-2\end{pmatrix} }}.
Note: In the Menu view cas.svg CAS View undefined variables can be used as well.
Example:
Element[{{a, b, c}, {d, e, f}}, 2, 3] yields f, the third element of the second row of \mathrm{\mathsf{ \begin{pmatrix}a&b&c\\d&e&f\end{pmatrix} }}.
Element[ <List>, <Index1>, <Index2>, ...]
Provided list 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] yields 3, Element[L, 2, 2] yields {7, 8}.
