Detailed Description

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

Centroidal momentum residual.

This residual function defines the centroidal momentum tracking as \(\mathbf{r}=\mathbf{h}-\mathbf{h}^*\), where \(\mathbf{h},\mathbf{h}^*\in~\mathcal{X}\) are the current and reference centroidal momenta, respectively. Note that the dimension of the residual vector is 6. Furthermore, the Jacobians of the residual function are computed analytically.

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