Linear least squares problems with additional constraints and an application to scattered data approximation. (English) Zbl 1281.65064
Summary: We construct generalized inverses to solve least squares problems with partially prescribed kernel and image spaces. To this end, we parameterize a special subset of all $$(1, 3)$$-generalized inverses, and analyze their properties. Furthermore, we discuss an application to scattered data approximation where certain $$(1, 3)$$-generalized inverses are more adequate than the Moore-Penrose inverse.
