Abstract
A system for estimating on-line a set of mathematical model parameters is disclosed. The system includes a control circuit and a number of sensors electrically coupled to the control circuit. The control circuit is configured to update a group of matrix cells of a data matrix in response to receiving sensory data from the number of sensors and determine the model parameters based on the updated data matrix.
