trackpy.motion.diagonal_size #715

Open Rory235 opened 1 year ago

Rory235 commented 1 year ago

Just wondering does the code trackpy.motion.diagonal_size calculate the gradient of a trajectory? If so how does it do this?

Following up on this, what does the lambda do it the many_trajectories.groupby('particle').filter(lambda x: tp.diagonal_size(x) > 5)
