Description

• 

The Expand function is a placeholder for representing the expand function. It is used in conjunction with mod, or evala, which define the coefficient domain as described below.

• 

The call evala(Expand(a)) expands products in a where a may contain algebraic numbers and functions defined by RootOfs or radicals. See evala/Expand for more information.

• 

The call Expand(a) mod p expands products in a over the integers mod p where a may contain RootOfs or radicals representing algebraic extensions.
