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}.
