This functions corrects the vector field to describe the inverse transformation of a given input vector field

Parameters

other	the vector field this one should be inverse of
tol	tolerance for inverse accuracy
maxiter	maximum number of interations for one vector to be optimized

update_by_velocity()

void C2DFVectorfield::update_by_velocity	(	const C2DFVectorfield &	velocity_field,
		float	time_step )

Update this vector field by using a velocity field

Parameters

velocity_field	the velocity field
time_step	the time step to be used for the update
