check for a RootOf data structure that is the collection of roots of an expression

 

Calling Sequence

Parameters

Description

Examples

Calling Sequence

type(expr, abstract_rootof)

Parameters

expr

-

any expression

Description

• 

The type(expr, abstract_rootof) function returns true if expr is the abstract collection of all the roots of an expression that uses a RootOf data structure. Otherwise, false is returned.

  

This function recognizes two forms of roots.

1. 

RootOf(expr) where expr is an algebraic expression

2. 

RootOf(expr, label = L) where expr is an algebraic expression, and L is any expression

  

If extra arguments are included in the call to type(expr, abstract_rootof), they are ignored.

Examples

typeRootOfx24x+71,abstract_rootof

typeRootOfx24x+71,index=1,abstract_rootof

false

(2)

true

(3)

typeRootOfx24x+7,2.+1.732050808I,abstract_rootof
