CASA Function: independentVariables
Computes a set of independent variables.
Calling Sequence:
- s := independentVariables(A)
Parameters:
- A : algset("impl")
- An algebraic set in implicit representation.
Result:
- s : set(name)
- a maximal set of independent variables of the algebraic set
Description:
- The function computes a maximal set of independent variables for an algebraic set in implicit form. The dimension of the algebraic set is exactly the number of independent variables.
Examples:
> a := mkImplAlgSet([x^2-3*x*y^2-7*y^3, x^2-z^2-1],[x,y,z]);
> independentVariables(a);
