Detailed Description

Implementation of constraint specific to a locked joint.

The implicit formulation as defined in class Implicit is given by

\begin{equation} h (\mathbf{q}) = q_{out} - value \end{equation}

where \(value\) is an element of the configuration space of the locked joint passed to method create.

Note that \(h\) takes values in \(\mathbf{R}^{nv}\) where \(nv\) is the dimension of the joint tangent space.

The explicit formulation is given by

\begin{equation} q_{out} = value + rhs \end{equation}

where coordinates of \(rhs\) corresponding to comparison types different from Equality are set to 0.

As such, the relation between the explicit formulation and the implicit formulation is the default one.
