◆ inverse_eval()

Eigen::VectorXd polyfem::solver::CompositeParametrization::inverse_eval ( const Eigen::VectorXd &  y) const

Eval x = f^-1 (y).

This is not a strict inverse in mathematical sense, one may choose "reasonable" x even if f is not one-to-one.

Parameters
[in]yy.
Returns
x.
Exceptions
std::runtime_errorThrow if inverse not implemented or is impossible.
