This is documentation for Mathematica 8, which was
based on an earlier version of the Wolfram Language.

• Functions with attribute Listable are automatically threaded over lists.
• All the elements in the specified args whose heads are h must be of the same length.
• Arguments that do not have head h are copied as many times as there are elements in the arguments that do have head h. »
• Thread specifies arguments using the standard sequence specification:
 All all elements None no elements n elements 1 through n -n last n elements {n} element n only {m,n} elements m through n inclusive {m,n,s} elements m through n in steps of s
Convert equations for lists to lists of equations:
Apply a function to both sides of an equation:
 Out[1]=
 Out[2]=
 Out[3]=

Convert equations for lists to lists of equations:
 Out[1]=

Apply a function to both sides of an equation:
 Out[1]=
 Scope   (9)
By default, thread over all arguments:
Thread over the first two arguments only:
Thread over the last two arguments only:
Thread over arguments 2 through 4:
Elements that are not lists are repeated:
 Applications   (3)
Build a list of rules:
Equate coefficients in a polynomial equation:
Alternatively, use SolveAlways:
Form pairs with a constant second element:
