[tiny suggestion] In Kalman Filter, nullify `corrected` after `predict()`
This is actually a suggestion to org.hipparchus.filtering.kalman.AbstractKalmanFilter
.
After line 59, simply add corrected = null;
.
Usually after doing a prediction, the old correction becomes useless.
It can help prevent using wrong data when one forgets to correct()
after predict()
. It seems not affect all other functions.
