The primary implementation is a (more or less) direct extension of the batch method for ordinary least squares. The software ensures P(t) is a positive-definite matrix by using a square-root algorithm to update it .The software computes P assuming that the residuals (difference between estimated and measured outputs) are white noise, and the variance of these residuals is 1.R 2 * P is the covariance matrix of the estimated parameters, and R 1 /R 2 is the covariance matrix of the parameter changes.

Recursive Least-Squares (Split RLS) algorithm can perform the approximated RLS with O(N) complexity for signals having no special data structure to be exploited (e.g., the signals in multichannel adaptive filtering applications, which are not shifts of a single-channel signal data), while avoiding the high compu- tational complexity (0( N2)) required in the conventional RLS algorithms. The block supports several estimation methods and data input formats.
