Abstract
A new generalized inverse of a singular and/or rectangular matrix is constructed by utilizing the Moore-Penrose generalized inverse. If this new inverse is used for solving a system of linear equations then it yields a solution vector with good resolution and small errors. Such solutions are particularly useful in remote sensing of atmospheric temperature profiles by satellites.
Zusammenfassung
Eine neue verallgemeinerte Inverse einer singulären und/oder rechteckigen Matrix wurde konstruiert unter Verwendung der Moore-Penrose verallgemeinerten Inversen. Wenn diese neue Inverse zur Lösung eines Systems von linearen Gleichungen angewandt wird, liefert sie einen Lösungsvektor mit guter Auflösung und kleinen Fehlern. Solche Lösungen sind besonders nützlich für die Ferndeutung von atmosphärischen Temperaturen via Satelliten.
