How to use

Library is supporting up to 3 values smoothened from a stream.

(float) stream

KalmanRx.createFrom1D(floatObservable.map(e -> e.value))
    .subscribe(value->{}, Throwable::printStackTrace);

(float, float) stream

KalmanRx.createFrom2D(floatObservable.map(e -> e.values))
    .subscribe(values->{}, Throwable::printStackTrace);

(float, float, float) stream

KalmanRx.createFrom3D(floatObservable.map(e -> e.values))
    .subscribe(value->{}, Throwable::printStackTrace);
