apply_jacobian()

Eigen::VectorXd polyfem::solver::BSplineParametrization2DTo3D::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::BSplineParametrization2DTo3D::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::BSplineParametrization2DTo3D::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.

Definition at line 138 of file SplineParametrizations.cpp.

size()

int polyfem::solver::BSplineParametrization2DTo3D::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.
