Array

Array[f, n]: returns the n-element list {f[1], ..., f[n]}.
Array[f, n, a]: returns the n-element list {f[a], ..., f[a + n]}.
Array[f, {n, m}, {a, b}]: returns an n-by-m matrix created by applying f to indices ranging from (a, b) to (a + n, b + m).
Array[f, dims, origins, h]: returns an expression with the specified dimensions and index origins, with head h (instead of List).
