capytaine.bodies.dofs.add_dofs_labels_to_matrix(dof_names, matrix)

Helper function turning a bare matrix into a matrix labelled by the name of the dofs, to be used for instance for the computation of RAO.

capytaine.bodies.dofs.add_dofs_labels_to_vector(dof_names, vector)

Helper function turning a bare vector into a vector labelled by the name of the dofs, to be used for instance for the computation of RAO.

capytaine.bodies.dofs.normalize_name(name)

capytaine.bodies.dofs.rigid_body_dofs(only=None, rotation_center=None)

Pass this to FloatingBody initializer to give it rigid body dofs.

Parameters:

• only (sequence of str, optional) – list of the name of the rigid body dofs to be included. By default: all six of them

• rotation_center (np.array, optional) – the center for the definition of the rotations
