◆ apply_jacobian()

Eigen::VectorXd polyfem::solver::BSplineParametrization1DTo2D::apply_jacobian	(	const Eigen::VectorXd &	grad_full,
		const Eigen::VectorXd &	x
	)		const

overridevirtual

Apply jacobian for chain rule.

Let g(y) = g(f(x)). Given ∂g/∂y, compute ∂g/∂x = ∂g/∂y * ∂y/∂x.

Parameters

[in]	grad_full	∂g/∂y.
[in]	x	Where ∂g/∂x is evaluated.

Returns: ∂g/∂x.

Implements polyfem::solver::Parametrization.

◆ eval()

Eigen::VectorXd polyfem::solver::BSplineParametrization1DTo2D::eval ( const Eigen::VectorXd & x ) const

overridevirtual

Eval y = f(x).

Parameters

[in] x x.

Returns: y.

Implements polyfem::solver::Parametrization.

Here is the call graph for this function:

◆ inverse_eval()

Eigen::VectorXd polyfem::solver::BSplineParametrization1DTo2D::inverse_eval ( const Eigen::VectorXd & y )

overridevirtual

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] y y.

Returns: x.

Exceptions

std::runtime_error Throw if not implemented.

Reimplemented from polyfem::solver::Parametrization.

◆ size()

int polyfem::solver::BSplineParametrization1DTo2D::size ( const int x_size ) const

inlineoverridevirtual

Compute DOF of y given DOF of x.

Parameters

[in] x_size The DOF of x.

Returns: DOF of y.
