Element( ,  )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 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( , ,  )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 begin{pmatrix}1&3&20&3&-2end{pmatrix}.
Note: In the 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 begin{pmatrix}a&b&cd&e&fend{pmatrix}.

Element( , , , ...)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}}}. Geogebra 3d CalculatorThen Element(L, 1, 2, 1) yields 3, Element(L, 2, 2) yields {7, 8}.
Note:Geogebra DownloadThis command only works, if the list or matrix contains elements of one object type (e. g. only numbers or only points).
