1. A system for estimating a set of mathematical model parameters, the system comprising: at least one sensor configured to produce sensory data; and a control circuit producing at least one control parameter, the control circuit maintaining a mathematical model as a function of a number of system operating conditions including either of the sensory data produced by the at least one sensor and the at least one control parameter as well as the set of mathematical model parameters, the control circuit responsive to the number of system operating conditions to periodically update a group of matrix cells of a data matrix, and to estimate the set of mathematical model parameters based on the updated data matrix.
