ConstantArray

generates a list of n copies of the element c.

generates an

array of nested lists containing copies of the element c.

ConstantArray[c, n, SparseArray] gives the constant array as a SparseArray object.

A deeply nested constant array:

Set up an array to use as storage in a program:

Numerically solve

using Euler's method:

Find the sum of the elements in a list:

This can also be done with Total:

Use a vector of ones to see the effects of conditioning on the solution of a linear system:

The solution at machine precision has significant errors:

At higher precision, the solution is much better:

has Dimensions[dims]:

is equal to SparseArray

Normal[s] is identical to ConstantArray

is equivalent to Apply[Table[c, ##]&, Map[List, dims]]:
