Array
(Built-in Mathematica Symbol) Array[f, n] generates a list of length n, with elements f[i]. Array[f, {n_1, n_2, ...}] generates an n_1*n_2*... array of nested lists, with elements f[i_1, i_2, ...]. ...
Version 6.0 added a collection of carefully optimized functions to Mathematica's powerful arsenal of numerical handling capabilities.
Unicode: 220B. Alias: Esc mem Esc. Infix set relation operator. x ∋ y is by default interpreted as ReverseElement[x,y]. Not the same as \[SuchThat].
ButtonBox[boxes] is a low-level box construct that represents a button in a notebook expression.
ListPlay[{a_1, a_2, ...}] creates an object that plays as a sound whose amplitude is given by the sequence of levels a_i.
WignerD
(Built-in Mathematica Symbol) WignerD[{j, m_1, m_2}, \[Psi], \[Theta], \[Phi]] gives the Wigner D-function D_m_1^m_2, j(\[Psi], \[Theta], \[Phi]).WignerD[{j, m_1, m_2}, \[Theta], \[Phi]] gives the Wigner ...
Permutations[list] generates a list of all possible permutations of the elements in list. Permutations[list, n] gives all permutations containing at most n ...
MapIndexed[f, expr] applies f to the elements of expr, giving the part specification of each element as a second argument to f. MapIndexed[f, expr, levelspec] applies f to ...
MatrixQ
(Built-in Mathematica Symbol) MatrixQ[expr] gives True if expr is a list of lists or a two-dimensional SparseArray object that can represent a matrix, and gives False otherwise. MatrixQ[expr, test] gives ...
NestWhileList[f, expr, test] generates a list of the results of applying f repeatedly, starting with expr, and continuing until applying test to the result no longer yields ...
