Detailed Description

The ForwardDynamicsMM class calculates the forward dynamics using the motion equation based on the generalized mass matrix. The class is mainly used for a body that has high-gain mode joints. If all the joints of a body are the torque mode, the ForwardDynamicsABM, which uses the articulated body method, is more efficient.
