CASA Function: mkImplAlgSet

Creates an algebraic set given in its implicit representation.

Calling Sequence:

• A := mkImplAlgSet(repr,vars)
• A := mkImplAlgSet(repr,vars,attr)

Parameters:

repr : list(polynom(casaCoeffType, vars))

• list of polynomials in vars with coefficients of type casaCoeffType.

vars : list(name)

• list of variables

attr : list(equation)

• list of initial attributes

Result:

A : algset("impl")

• A Maple object representing an algebraic set.

Description:

• The function works as an input interface to the datatype algebraic set. It takes as argument a list or set of polynomials whose common zeros define the algebraic set.

Examples:

> A := mkImplAlgSet([x^2+y^2-4],[x,y]);
