Array

Array[f, n] generates a list of length n, with elements f[i].

Array[f, n, r] generates a list using the index origin r.

Array[f, {n1, n2, ...}] generates an n1×n2×... array of nested lists, with elements f[i1, i2, ...].

Examples

Generate a simple array:

Array[f, 4]
(* {f[1], f[2], f[3], f[4]} *)

Generate a 2×3 matrix:

Array[a, {2, 3}]
(* {{a[1,1], a[1,2], a[1,3]}, {a[2,1], a[2,2], a[2,3]}} *)
