Inheritance diagram for hexed::Diff_sq:

Public Member Functions
	Diff_sq (const Domain_func &, const Domain_func &)
	parameters are the functions you want to compute the difference of. Must return values of same size.

	Diff_sq (Domain_func &&, const Domain_func &)=delete
	can't accept temporaries or else dangling reference

	Diff_sq (const Domain_func &, Domain_func &&)=delete

	Diff_sq (Domain_func &&, Domain_func &&)=delete

int	n_var (int n_dim) const override
	number of output variables when called on `n_dim`-dimensional input

std::vector< double >	operator() (std::vector< double > point_pos, double point_time, std::vector< double > state) const override

Public Member Functions inherited from hexed::Domain_func
std::vector< double >	operator() (Element &, const Basis &, int i_qpoint, double time) const override

std::vector< double >	operator() (std::vector< double > pos, double time, std::vector< double > state, std::vector< double > outward_normal) const override
	`normal` is surface unit normal vector pointing out of the surface (into the domain).

Public Member Functions inherited from hexed::Output_data
virtual std::string	variable_name (int n_dim, int i_var) const
	name of `i_var`th variable (for plotting) when called on `n_dim`-dimensional input
