# Saver

This is a helper class designed to allow you to save the state of the Kalman filter for each epoch. Each instance variable is stored in a list when you call save().

This class is deprecated as of version 1.3.2 and will be deleted soon. Instead, see the class filterpy.common.Saver, which works for any class, not just a KalmanFilter object.

Example

    saver = Saver(kf)
    for i in range(N):
        kf.predict()
        kf.update(zs[i])
        saver.save()

    saver.to_array() # convert all to np.array

    # plot the 0th element of kf.x over all epoches
    plot(saver.xs[:, 0])
