title: Solution of the damped least-squares problem by using a combination of eigenvalue and singular value decompositions.
abstract: A combination of eigenvalue and singular value decompositions are used to solve the normal equation. An aspheric lens design that uses a 14-term power series aspheric for each surface is presented.
