Array

Array
generates a list of length n, with elements .
Array
generates an array of nested lists, with elements .
Array
generates a list using the index origins (default ).
Array
uses head h, rather than List, for each level of the array.

Use index origin instead of :
Start with indices and instead of :
In[1]:=
Click for copyable input
Out[1]=
In[2]:=
Click for copyable input
Out[2]=

Generalizations & Extensions   (2)
Use to pick up a sequence of indices:
Use Plus instead of List to combine elements:
Applications   (4)
matrix of 0s:
Totally antisymmetric tensor:
Lower-triangular matrix:
Matrix with generic symbolic entries:
Use it to see the effects of some linear algebra functions:
Properties & Relations   (3)
ConstantArray and Array are equivalent:
When c is a machine number, ConstantArray is much faster for large arrays:
Array can be generated using Table:
Set up the Table limit specifications:
Use Apply to splice them into a Table command:
The result is identical to the array generated using Array:
SparseArray gives a sparse representation of Array:
The results are Equal:
The objects are not identical, but the represented arrays are:
Neat Examples   (3)
Array of powers:
Array of GCDs:
Array of arrays:
