Kalman filtering via RcppArmadillo -- based on a R and C++ port of the EKF/UKF toolbox for Matlab
Static Sine Signal And Noisy Measurement
This example is not described in the pdf manual, but included as demo kf_sine_demo.m within the EKF/UKF sources. A signal is provided via a sine wave plus random noise, and a linear Kalman Filter is used to smooth and filter the series. Our variant demo/kf_sine_demo.R reproduces the demo via the following chart
Continuous Wiener-Process Acceleration
This demo is described in detail in Section 2.2.4 on pages 11 to 15 of the EKF/UKF Documentation; the animation is part of the corresponding Matlab code in kf_cwpa_demo.m. We show the two final charts which provide animations of the smoothing and filtering in our version demo/kf_cwpa_demo.R:
Working, but still far from complete. We currently support two demo scripts based on linear smoothers and filters. Additional functions should get added over time.
