## Public Member Functions

Eigen::VectorXd operator() (const Eigen::VectorXd &p) const
Value of the function at a specified point. More...

std::size_t amb_d () const
Returns the (ambient) domain dimension.

std::size_t cod_d () const
Returns the codomain dimension.

Eigen::VectorXd seed () const
Returns a point on the surface. This seed point is only one of two necessary seed points for the manifold tracing algorithm. See the method seed2() for the other point.
