|The general least squares process can be used to solve a set of equations for a set of unknowns. The only requirement is that there are at least as many equations as there are unknowns. This paper (in html and PDF formats) provides a new description of least squares that describes the process in a simple, straightforward manner. A complete derivation of the method is not provided, only a functional description. Familiarity with matrices and partial derivatives is assumed.
