Detailed Description

template<typename _Scalar>
class crocoddyl::ResidualModelStateTpl< _Scalar >

State residual.

This residual function defines the state tracking as \(\mathbf{r}=\mathbf{x}\ominus\mathbf{x}^*\), where \(\mathbf{x},\mathbf{x}^*\in~\mathcal{X}\) are the current and reference states, respectively, which belong to the state manifold \(\mathcal{X}\). Note that the dimension of the residual vector is obtained from StateAbstract::get_ndx(). Furthermore, the Jacobians of the residual function are computed analytically.

As described in ResidualModelAbstractTpl(), the residual value and its derivatives are calculated by calc and calcDiff, respectively.
