Using Array and Table Functions in Mathematica. Which is best when

Question

I have been mostly a Table functions user in mathematica. However I have noticed that in several examples where I used Array instead of Table to express the same result, it ran

Answer 1

Your statement:

However I have noticed that in several examples where I used Array instead of Table to express the same result, it ran markedly faster, especially as the dimension of table grew larger.

is not usually true for one-dimensional arrays. Take a look:

Cl;
Needs["PlotLegends`"]
$HistoryLength = 0;
a = 10^8;
arr = {}; tab = {};
Do[(
   arr = {First@Timing@Array[# &, a], arr};
   tab = {First@Timing@Table[i, {i, a}], tab};
   ), {10}];

ListLinePlot[{Flatten@arr, Flatten@tab}, 
 AxesLabel -> {Style["Iteration", 14], Style["Time", 14]}, 
 PlotLegend -> {Style["Array", 14], Style["Table", 14]}, 
 PlotRange -> {{0, 10}, {1.6, 2}}]
