WebIn the terminology of total least squares (TLS), this solution is a direct weighted total least squares (WTLS) approach. For the most general weighting case, considering a full dispersion matrix of the observations that can even be singular to some extent, a new iterative solution based on the ordinary iteration method is developed.

Our aim is to to solve the least-squares problem. A x = y. or equivalently, U 1 Σ V t x = y. It is not necessary to multiply both sides by A t but you have not done a mathematical mistake by doing that multiplication. However, numerical analysts would not happy if you do that multiplication. Pre-multiply by U 1 t and use the property U 1 t ... iphone xs max doing things by itself
