Detailed Description

Full discretization grid specialization for SE2.

This class defines the basis for full discretization grids similar to corbo::FullDiscretizationGridBase. However, the main difference is, that this grid requires the first three state components to be embedded in SE2. Whereas the first two states are ordinary real numbers on (-inf, inf), the third component must remain in [-pi, pi).

Therefore, the minimum dimension state dimension is 3. However, larger dimensions are allowed, but the related state components are considered as standard real numbers on (-inf, inf).

Note the full discretization grid currently supports only finite difference collocation to discretize the continuous time dynamics. Full discretization is also possible with multiple shooting and (expicit) numerical integration, but for this purpose we need to specialize corbo::ShootingGridBase for SE2.
