I'd say even more, the Kalman Filter is linear, if you have the samples up to certain time $T$, you can write the Kalman filter as weighted sum of all previous and the current samples. For use with our data, we used a simple form of a Kalman filter for a linear dynamic. You’ll learn how to perform the prediction and update steps of the Kalman filter algorithm, and you’ll see how a Kalman gain incorporates both the predicted state estimate (a priori state estimate) and the measurement in order to calculate the new state estimate (a posteriori state estimate). This is code implements the example given in pages 11-15 of An Introduction to the Kalman Filter by Greg Welch and Gary Bishop, University of North Carolina at Chapel Hill, Department of Computer Science. The more you understand the mathematical model of your situation, the more accurate the Kalman filter's results will be.
