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,n,{a,b}]

generates a list using n values from a to b.

Array[f,{n1,n2,…}]

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

Array[f,{n1,n2,…},{r1,r2,…}]

generates a list using the index origins ri (default 1).

Array[f,{n1,n2,…},{{a1,b1},{a2,b2},…}]

generates a list using ni values from ai to bi.

Array[f,dims,origin,h]

uses head h, rather than List, for each level of the array.
